[Bf-python] threading needed for pyverse

This is not a problem, it is necessary, you know.  Specially with better
integration, scripts, scriptlinks and gameengine scripts, and possibly
many scripts running in a single session, more than one script at a
time.

The Blender.Registry module is there to solve persistence issues, it'll
keep data in a dictionary that won't be discarded after each script run.

You can run more than one script at once, one per text window, each with
its own global dict (or the same if the user decided to keep the global
dict -- there's a function for this in the main Blender module).  The
current system was just hardcoded to use SpaceTexts.  With the new
SpaceScript this changes.
