Calling AssFile::Save/Load from multiple threads (even on different
objects) was not safe due to that is uses SubtitleFormat internally,
which was inheriently thread-unsafe. To fix this, change
SubtitleFormat's interface to support immutable implementations, and
make all of the current implementations immutable.
This isn't a perfect solution - making a subtitle format implemented in
lua immutable would be rather difficult - so at some point in the future
SubtitleFormat should probably be changed to a factory which returns new
objects from GetReader/GetWriter.

Rather than setting the default script resolution to 640x480, leave it
unset in new files. When video is opened, if the user has not already
manually set a script resolution, automatically use the video's
resolution as the script resolution. If the user has and the set
resolution is not a multiple of the video resolution, use the old prompt
for updating it.
This eliminates the confusing prompt about mismatched resolutions when
opening video with a new file while hopefully resulting in users using
the correct resolution more often.

Document all of the SubtitleFormat methods.
Add default implementations of CanReadFile and CanWriteFile that check
against the appropriate wildcard list.
Clean up and simplify a lot of very odd code.
Throw typed exceptions in all subtitle readers rather than strings.

Switch to a bitmask with much more finely-grained information about what
changed in the commit, fixing a few potential correctness problems and
significantly improving the performance of several scenarios where commits
are spammed very frequently.

Rather than everything having to separately commit changes to the ass
and then tell the subs grid to notify various parts of Aegisub about the
changes, committing the AssFile now triggers an event which objects
listen for.
AssFile::Commit now also has an argument to indicate what sorts of
changes were made to the file. For now these types are very broad.

Don't display error messages and try other providers when the user
cancels loading a file.
Remove files from the MRU lists if they can't be found.
Closes#717.

This happens to fix most of the undo issues, as it's now much harder to
have uncommitted changes to the file.
Closes#355 and #586.

Make the undo and redo stacks non-static members of AssFile, making it
theoretically possible to have multiple open AssFiles with working undo.
Slightly improve tracking of whether the file is modified: saving,
making a change, then undoing the change now results in the file being
shown as unmodified as with most programs with undo.
Add basic undo coalescing support.

Kill vfr.h and vfr.cpp and use the libaegisub versions of them instead.
Rather than the globals VFR_Input and VFR_Output, everything related to
frame rate is now part of the video context. Most things which used to
use VFR_Output now call VideoContext::TimeAtFrame etc.; video providers,
rather than modifying VFR_Input directly, now have getters for their
frame rates which VideoContext calls. Read-only public access to
VFR_Input and VFR_Output are still provided (hopefully temporarily) for
a few things which were awkward to do through VideoContext.
The Avisynth provider now might correctly handle VFR MKVs which can be
opened with DirectShowSource but not DSS2.
Rework keyframe handling as well, so that it continues to match the vfr
handling in design and implementation.
