== Animated Transforms to Deltas ==

Added operator to convert animation for standard object transforms
(i.e. loc/rot/scale) to delta transforms.
This can be accessed from the Object -> Transform -> Animated
Transforms To Deltas menu entry in the 3D View.

Since the situation which causes this is quite common (especially for
motion-graphics type applications), where users animate some object
first and then decide to duplicate this and place it around the place
in different locations, it's probably important that we have some
support for this kind of thing. Newbies with the "help, all my anmated
duplicates disappear" problem are recommended to use this operator
from hereon in.
