Split int validating and double validating into two separate classes.
Make double parsing, validating and stringifying locale-aware. This is
far more complicated than it needs to be due to that Aegisub's locale
handling is a total mess.
Use DoubleValidator rather than wxFloatingPointValidator, because the
latter doesn't work with Aegisub's locale mess (on OS X it uses the C
locale for some things, and the locale reported by CoreFoundation for
others).
Closes#1568.
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.
Character counts are a pretty terrible measure of anything, but it's
still the main measure of length used in most subtitling standards
(because subtitling standards are written under the assumption that the
tools are terrible (which is generally an accurate assumption)).

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.
It is very unlikely that anyone has ever actually used ASS2 for
anything, and in practice it was not usable anyway as the bottom margin
was always either ignored or blindly overwritten.
