BPython:

- fixed bug #1882: http://projects.blender.org/tracker/?func=detail&atid=125&aid=1882&group_id=9
    Crash / hang when changing meshes that had edge data.  The mesh->totedge value was not being set to 0.  Reported by jms, thanks.
- fixed bug #1780: https://projects.blender.org/tracker/index.php?func=detail&aid=1780&group_id=9&atid=125.
    Deleting a Text that was being used as script link crashed Blender.  Added a check to unlink the Text from eventual script links when it gets removed.  Reported by kaito, thanks.
- doc updates (one related to bug #1807: http://projects.blender.org/tracker/?func=detail&atid=125&aid=1807&group_id=9 , actually a little misleading word in the NMesh doc: you can get the subsurfed mesh with NMesh.GetRawFromObject, but it's the display subdivision level that counts).
