Fix T39806: Koro rig (Caminandes) wrong in master, worked in 270(a).

Edit existing animsys_refactor module to make able to execute more complex conversions
('to' can now be a callback, instead of a simple prop name), and add a new
Update Animated Transform Constraints operator that uses it to handle complex
conversion for this constraint (drived or animated properties).

Note this operator has to be called manually (from 'space' menu), will make this clear
in release notes.

Also, similar changes made in 2.70 are *not* addressed by this script (would rather wrote
new operators as/if need arise, but Transform constraint looks much more sensible that the others).

This op should not remain in more than two or three releases anyway, imho.
