epy doc generator that runs inside blender2.5, in background mode.

Automatic support for...
* cross references to struct types
* extracts descriptions/names
* RNA "base" types are converted to python subclasses
* number min/max, string max length, array's, array lengths, valid enum types, readonly flag.
