Demo mode and BPython:

- small additions and fixes to enable the demo mode;

- Added sleep() to Blender.sys and 17 new functions to Blender.Window module:
    things to help demo script writing and as a bonus read / write access to Blender's input event queue;

- updates in docs, those interested please check Window.py in python/api2_2x/doc/ to read about the new Blender.Window functions.

----

Demo mode should be working well now for (I) playing rt animation -- aka ALT+A -- and (II) rendering pics and anims and playing anims.  I'll still add access to radiosity data and functions.

PS: Joseph Gilbert made (II) possible with the Scene.Render module he added for 2.32.  He's been coding great things for bpython, so I'd like to take the chance to point that and thank him here.
