BPython bug fixes:

- #2646 reported by Campbell: Python/Fileselector (moving from fileselector called by script to another space caused script to hang around open but not accessible)
http://projects.blender.org/tracker/?func=detail&atid=125&aid=2646&group_id=9

- #2676 reported by Wim Van Hoydonck: 2.37 python scripts gui: event 8 ignored (thanks Ton for discussing / pointing what to do, Ken Hughes for also working on a fix)
http://projects.blender.org/tracker/?func=detail&atid=125&aid=2676&group_id=9

- gui-less scripts with calls to progress bar inside fileselector callbacks didn't return to the previous space on exit (staying on Scripts win), requiring an event to do so (mouse movement, for example).  Quick fix for now, will rework a little after 2.37a for a better alternative, not needing to move to the Scripts win at all.

- added syntax colors access to Window.Theme module.

Scripts:

- updates by Jean-Michel Soler: svg2obj (svg paths import), tex2uvbaker, fixfromarmature;
- updates by Campbell Barton: obj import / export, console;
- tiny: converted vrml97 export to unix line endings;
- updates in ac3d exporter, help browser, save theme.

Thanks all mentioned above.
