Calling GetReverseUnicodePosition on the selection positioning after
calling SetText resulted in the conversions between UTF-8 indices and
wxString indices just being a very slow no-op.
Use boost::filesystem::path for all paths, and std::string for all other
strings, converting to/from wxString as close to the actual uses of wx
as possible.
Where possible, replace the uses of non-UI wxWidgets functionality with
the additions to the standard library in C++11, or the equivalents in
boost.
Move the path token management logic to libaegisub (and rewrite it in
the process).
Add a basic thread pool based on asio and std::thread to libaegisub.
This touches nearly every file in the project and a nontrivial amount of
code had to be rewritten entirely, so there's probably a lot of broken
stuff.
Nearly all of the files including main.h are doing so only for OPT_GET
and friends, which are rather unrelated to the main things that main.h
declares.

Note: The large jump in memory usage here is due to that the benchmark
is blocking the main thread, so at the end there are ~100 video frames
waiting to be displayed.
There's really no reason not to include it even if the right-click
wasn't on a word, and leaving it out can lead to confusing situations
when the dictionary file for the user's currently selected language
doesn't exist.
The syntax highlighting isn't especially slow, but the stylesneeded
event seems to be sent repeatedly until the styles aren't changed, so it
was pointlessly reparsing and restyling the text on every idle event.
Mostly just bugs in unreachable code and stylistic things, but there's a
few incorrect reachable things that were working by coincidence and
gratuitous dynamic_casts.
Although in absolute terms it does not take very long, loading the 18 MB
en_US thesaurus was about three quarters of Aegisub's total startup
time when opening with no command line arguments.
Originally committed to SVN as r6702.
This gives spellchecking and thesaurus support for the translation (and
syntax highlighting, but that usually won't be useful).
Originally committed to SVN as r6578.
With incomplete (or possibly incomplete for \r and \fn) tags at the end
of an override block, the text at the beginning of the next override
block was being incorrectly parsed as part of that tag.
Originally committed to SVN as r6317.
