Refactored.
Merged trunk and replaced 'use()' through 'include() in Lua files.
Made scripting.h much simpler.
Renamed FindFiles to ListDirectory and simplified it. This broke some stuff.
Fixed style.
All done.
- Removed use() and replace through include() in Lua.
- Refactored scripting.h/cc to be more modular and removed ScriptContainer.
- Replaced FileSystem::FindFiles through ListDirectory as the globbing did never
  work properly.
- The map now keeps it's filesystem (the file it was loaded from) around.
Do not reencode images in map on game save.
Fixed starting of the editor.
