- Some visual aesthetics
@ Fixed the "Release with revision lookup" config output directories

Added source code for Map Statistics plugin. Most simple plugin ever, see this source code to learn the very basics of making a Doom Builder 2 plugin. Lot of comments in the source code to explain why things are needed.

Removed changes for BZip2 and LZMA compression support (library is unstable, will have a look at this later)

- Fixed some property inheritance in DECORATE actors

@ Removed SlimDX note from about dialog. They don't care for me using SlimDX anyway, despite being their first user when they started that project :'(

- Removed an unused action

Added culture independent parsing code in TEXTURES/DECORATE parsers to fix problems reading values in different languages
