[Bf-python] API documentation patches for IPO, script links

[Ken Hughes]

Just in case everyone else is busy on something and didn't get around
to it, I uploaded two patches to the patch tracker which document the
addition of the "Render" script link and clean up some inconsistency
in the Ipo documentation:

https://projects.blender.org/tracker/index.php?func=detail&aid=2596&group_id=9&atid=127

Use or discard as appropriate.
