Primary goal of this commit is to fix an annoying issue - when processing and saving .blend files in background mode you lose their thumbnails, since it can only be generated with an OpenGL context. Solution to that is to read .blend thumbnail while reading .blend file (only done in background mode currently), and store it in Main struct. Also, this lead to removing .blend file reading code from thumb_blend (no need to have doublons). We now have a small interface in regular reading code area, which keeps it reasonbaly light by only reading/parsing header info, and first few BHead blocks. This makes code reading .blend thumbnail about 3 to 4 times slower than previous highly specialized one in blend_thumb.c, but overall thumbnail generation of a big .blend files folder only grows of about 1%, think we can bare with it. Finally, since thumbnail is now optionally stored in Main struct, it makes it easy to allow user to define their own custom one (instead of auto-generated one). RNA API for this was not added though, accessing that kind of .blend meta-data has to be rethought a bit on a bigger level first.
