BPython bug fixes:

- bug #2033 reported by Ken Hughes: Vertices of mesh parented to lattice is scaled incorrectly:
https://projects.blender.org/tracker/?func=detail&aid=2033&group_id=9&atid=125

- bug #2211 reported by German Alonso Tamayo (servivo): Add a vertex to a mesh with groups using a script and then edit that mesh hangs blender:
https://projects.blender.org/tracker/index.php?func=detail&aid=2211&group_id=9&atid=125

(#2211's hang was already fixed with previous commit, but this way should work better)

- doc updates (Ken reported missing info about Render slinks, thanks).
