Scripts:

- Campbell Barton updated his sel_same.py script;
- Added to Mesh scripts a call to Window.EditMode(0) to leave editmode before changing meshes.

BPython:
- small doc fixes / updates;
- added a call to undo_push_mesh inside Window.EditMode(0).

Mesh scripts could change the mesh but not the editmesh -- that would then overwrite the changed mesh.  Made all mesh scripts leave edit mode before changing a mesh.
