TODO:

*.upk (or *.kfm) with it's own filesystem (like in weapon packs)
add kf2 support in another steam library (Steam\steamapps\libraryfolders.vdf may help)
close the KFEditor window only after it stops writing to Launch.log to be able to show warnings
hooks (precompile, postcompile, prebrew, etc...)
improve error parser (class vs name mismatch, etc...)
manual brew config setting
