Tiny group-proxy update:

When you make proxy, the group-update tags should be set OK.

Symptom: you could not move proxy around until you set keys
in bones and advance frame.

Another feature request from the animation dept:

Relative shapekeys now allow to define the Shape it is relative to!
(It used to be relative with respect to the first key, which is still
default).

The reason for this feature is that keys don't always add together
well when they're all derived from the same base shape. A clear
example is hard to make... will wait for someone posting it.
