Buildsystem: Overhaul of the CMake buildsystem:

- utilize CMake for completely generating revision.h (kills off genrev and revision.h targets):
  - pull and set correct revision-ID/hash from Mercurial (hg) when using regular repository sourcetree
  - pull and set correct revision-ID/hash from archived releases (when pulled from googlecode)
  - set and use _BUILD_DIRECTIVE definition (earlier part of revision.h) as compiletime definition
- delete genrev and related buildsystems
  (now deprecated)
- Move some files around to adhere to buildsystem structure
Thanks to Shauren for figuring out the definition-behaviour for MSVC while he was in the shower
