Blender Git Loki

BPython:
- Small doc update in a script;
- Fixed bug #1742:
http://projects.blender.org/tracker/?func=detail&atid=125&aid=1742&group_id=9

It was an internal error in bpython. I was using G.main->script.last to find the currently running (if any) script, but this isn't reliable, we must check each open script to find out if one of them has the SCRIPT_RUNNING bitflag set.

Thanks intrr for reporting and blendix for pointing how to reproduce the bug. From my tests it should be working fine now.
