Port to AutoHotkey_L

I've ported these scripts to [AutoHotkey_L](http://l.autohotkey.net/):

* All script and localization files are converted to UTF-8.
* Executables can be run from a path containing Unicode characters.
* Custom charset conversion code is no longer necessary and is removed.
* ResHacker is no longer necessary and is removed.

This is still a 32-bit version.
