Trying to fix bug reported by Peter den Bak and Meino Christian Cramer (thanks!):

-- splash screen disappeared (duh, I did that!) and Blender quits upon exiting from some 225 games:

It was troublesome to find how to run demos in general with the screen correctly redrawn before they started, etc.  Ended up making the above error in screenmain().  About the games, I don't have them and will need some time to get the files for testing, but I'll do it, though only on linux.

BPython:
-- Window: added GetScreens, SetScreen and improved GetScreenInfo.
-- Object, NMesh: updated (added in NMesh) method getMaterials to return either only valid materials as before or also empty slots (as None).  This previous omission can be considered a bug, since it made info about materials incomplete / incompatible with face mat indices.  Thanks Yann Vernier for bringing this up and sending/proposing a patch that also fixed a bug related to assigning lists of materials with different lengths to obj and its mesh. setMaterials also accepts Py_None entries now, which become empty slots in Blender.
-- doc updates.
