* Added 3 missing functions, 2 of them called by blender/src/drawtext.c:

Callbacks registered with Draw.Register in Python are called now.
    That should fix submodule Blender.Draw.
* Added a few other missing functions to BPY_interface.c
* Finished implementing Get() function for Camera, Lamp, Image and Text:
    Both the .Get(name) and .Get() cases are handled now.
* Added function Blender.ReleaseGlobalDict():
    This function should give script writers control over whether the
    global Python Interpreter Dict should be cleared after the script is
    run (default is to clear).  This is a test.
