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.
