BGE PyAPI can now import text (within the blend-file)

Previously this only worked with the Blender API.
- bpy_internal_import small C file that Blender scripting and the game engine use.
- Tested with blender, blenderplayer, loading files
- Needed to use a hack to override the Main struct since the game engine doesn't set G.main
- when the sandbox is set, only internal scripts can be imported.
