Add macOS to travis

Previously, when reading font data, we only set FaceName to the matched font. When we are using some font with special font weight (e.g. @Source Han Sans J Heavy), if we do not correct the font weight in the LOGFONTW struct, then subsequent call to get_font_data will fall back to default font. This causes wrongly matching Arial.ttf to any font that does not provide standard font weights.

Instead of only correcting FaceName using the matched font, we simply use the first matched font, thus the FaceName, Weight, CharSet, etc. will all be correct. This also eliminates the memcpy.

 ## Building Aegisub
 
-### Windows
-
 Prerequisites:
 
-1. Visual Studio 2015 (the free Community edition is good enough)
-2. The June 2010 DirectX SDK (the final release before DirectSound was dropped)
-3. [Yasm](http://yasm.tortall.net/) installed to somewhere on your path.
-
-There are a few optional dependencies:
-
-1. msgfmt, to build the translations
-2. WinRAR, to build the portable installer
-3. InnoSetup, to build the regular installer
-
-All other dependencies are either stored in the repository or are included as submodules.
+1. CMake 3.14 or later (or you can use an older version by editing the first line in CMakeLists.txt, and download the missing `cmake/FindFontconfig.cmake` from [here](https://gitlab.kitware.com/cmake/cmake/blob/master/Modules/FindFontconfig.cmake)),
+2. Any compiling toolchain supported by CMake,
+3. All required dependencies, namely `libass`, `Boost`(with ICU support), `OpenGL`, `libicu`, `wxWidgets`, `zlib`. Additionally, `libiconv` is required on non-POSIX systems. `fontconfig` is required on non-Windows systems.
+4. Any optional dependencies, namely `ALSA`, `FFMS2`, `FFTW`, `Hunspell`, `OpenAL`, `uchardet`.
 
 Building:
 
-1. Clone Aegisub's repository recursively to fetch it and all submodules: `git clone --recursive git@github.com:Aegisub/Aegisub.git` This will take quite a while and requires about 2.5 GB of disk space.
-2. Open Aegisub.sln
-3. Build the BuildTasks project.
-4. Build the entire solution.
-
-You should now have a `bin` directory in your Aegisub directory which contains `aegisub32d.exe`, along with a pile of other files.
-
-The Aegisub installer includes some files not built as part of Aegisub (such as Avisynth and VSFilter), so for a fully functional copy of Aegisub you now need to copy all of the files from an installed copy of Aegisub into your `bin` directory (and don't overwrite any of the files already there).
-You'll also either need to copy the `automation` directory into the `bin` directory, or edit your automation search paths to include the `automation` directory in the source tree.
-
-After building the solution once, you'll want to switch to the Debug-MinDep configuration, which skips checking if the dependencies are out of date, as that takes a while.
-
-### OS X
-
-A vaguely recent version of Xcode and the corresponding command-line tools are required.
-Nothing older than Xcode 5 has been tested recently, but it is likely that some later versions of Xcode 4 are good enough.
-
-For personal usage, you can use homebrew to install almost all of Aegisub's dependencies:
-
-	brew install autoconf ffmpeg freetype gettext ffms2 fftw fribidi libass m4
-	brew install --devel --with-gc64 luajit
-	brew install --HEAD icu4c
-	brew link --force icu4c
-	brew link --force gettext
-	brew install --HEAD --c++11 --with-icu4c boost
-
-wxWidgets is located in vendor/wxWidgets, and can be built like so:
-
-	CPPFLAGS="$CPPFLAGS -D__ASSERT_MACROS_DEFINE_VERSIONS_WITHOUT_UNDERSCORES=1" \
-	./configure --disable-aboutdlg --disable-animatectrl --disable-aui --disable-any \
-	--disable-bannerwindow --disable-base64 --disable-calendar --disable-caret \
-	--disable-cmdline --disable-colourpicker --disable-compat28 --disable-config \
-	--disable-constraints --disable-datepick --disable-dctransform --disable-debugreport \
-	--disable-dialupman --disable-docview --disable-filehistory --disable-finddlg \
-	--disable-fs_archive --disable-fs_inet --disable-fs_zip --disable-fsvolume \
-	--disable-fswatcher --disable-gif --disable-help --disable-html --disable-ipc \
-	--disable-joystick --disable-jpeg --disable-largefile --disable-markup --disable-mdi \
-	--disable-mediactrl --disable-metafiles --disable-miniframe --disable-notifmsg \
-	--disable-numberdlg --disable-pcx --disable-pnm --disable-postscript \
-	--disable-prefseditor --disable-printarch --disable-progressdlg --disable-propgrid \
-	--disable-protocol --disable-protocols --disable-rearrangectrl --disable-ribbon \
-	--disable-richtext --disable-richtooltip --disable-snglinst --disable-sockets \
-	--disable-sockets --disable-sound --disable-splash --disable-splines \
-	--disable-std_iostreams --disable-svg --disable-tarstream --disable-tiff \
-	--disable-tipdlg --disable-tipwindow --disable-url --disable-webkit --disable-webview \
-	--disable-wizarddlg --disable-xrc \
-	--enable-geometry --enable-imaglist --enable-listctrl --enable-stc --with-cocoa \
-	--with-libpng=yes --with-macosx-version-min=10.9 \
-	--with-opengl \
-	--without-libjpeg --without-libtiff --without-regex \
-	&& make
-
-Once the dependencies are installed, build Aegisub with `autoreconf && ./configure --with-wxdir=/path/to/Aegisub/vendor/wxWidgets && make && make osx-bundle`.
-`autoreconf` should be skipped if you are building from a source tarball rather than `git`.
+1. If you decided to build from source:
+```shell
+git clone https://github.com/wangqr/Aegisub.git  # No --recursive is needed
+cd Aegisub
+./build/version.sh .  # This will generate build/git_version.h
+```
+2. Make an empty directory to hold build outputs:
+```shell
+mkdir build-dir
+```
+3. Build the project using CMake. Use either cmake-gui, or the command line:
+```shell
+cd build-dir
+cmake ..
+make
+```

+  <description>
+    <_p>Aegisub is a free, cross-platform open source tool for creating and modifying subtitles. Aegisub makes it quick and easy to time subtitles to audio, and features many powerful tools for styling them, including a built-in real-time video preview.</_p>
+    <_p>Aegisub was originally created as a tool to make typesetting, particularly in anime fansubs, a less painful experience. At the time of the start of the project, many other programs that supported the Advanced Substation Alpha format lacked (and in many cases, still lack; development on several competing programs have since been dropped for various reasons completely unrelated to Aegisub) many vital functions, or were too buggy and/or unreliable to be really useful.</_p>
+    <_p>Since then, Aegisub has grown into a fully fledged, highly customizable subtitle editor. It features a lot of convenient tools to help you with timing, typesetting, editing and translating subtitles, as well as a powerful scripting environment called Automation (originally mostly intended for creating karaoke effects, Automation can now be used much else, including creating macros and various other convenient tools).</_p>
+    <_p>Some highlights of Aegisub:</_p>
+    <ul>
+      <_li>Simple and intuitive yet powerful interface for editing subtitles</_li>
+      <_li>Support for many formats and character sets</_li>
+      <_li>Powerful video mode</_li>
+      <_li>Visual typesetting tools</_li>
+      <_li>Intuitive and customizable audio timing mode</_li>
+      <_li>Fully scriptable through the Automation module</_li>
