Py API (GSoC): Second merging commit

Rough summary of fixes/changes:
- Blender Py API: GameLogic -> bge.logic
- Blender Py API: Implemented missing KX_PYATTRIBUTE_TODOs and -DUMMYs.
- Fix for [#22924] KX_PolygonMaterial.diffuse does not return expected list[r,g,b]
- Py API: Renaming _owner attribute of mathutils classes to owner.
- Fix some minor errors in mathutils and blf.
- Enabling game engine autoplay again based on a patch by Dalai:
  * The biggest 3D view in the open scene is used, if there is none, blender opens the file normally and raises an error.
  * The 3D view are is made fullscreen.
  * Quad view, header, properties and toolbox panel are all hidden to get the maximum view.
  * If the game engine full screen setting is set, the game starts in fullscreen.
- Fix for ipo conversion on file transition in the game engine.
