tested as working rev 31965

- comforming after my commit in bf-blender:
  - removed the categories from addons names
  - made 'version' a tuple of integers
  - added 'api' field
  - formatted wiki and trackers pages and added where needed (empty pages are yet to be written by the authors though)

- more conforming:
  - 1 tab = 4 spaces

- please check everything is fine in case I made some gross mistake

- some conforming
