Blender Git Loki

BPython:
- Added Blender.UpdateMenus() + doc: so scripts can automatically update Blender menus when they create (or download or whatever) new scripts to be registered.
- Removed a long deprecated function from the Blender module (release dict).

Matt (broken) mentioned the UpdateMenus function a couple weeks ago. I also updated the Save Current Theme script to use it. This is all related to his ideas to use scripts to save and restore themes and e.g. render presets.
