nice trick for beautiful fk widgets

[Alessandro Padovani]

I believe this is mainly useful for fk rigs. I just noticed that if we set ik limits then they are displayed in the viewport, even if ik is not active. This may be a nice trick to get a beautiful representation of the fk limits when the user selects the bone for posing. That is, we just copy the fk limits over ik, even if ik is not used. So may be we could add an option for “display fk limits”.

Below an example with G2F with the daz rig.

Implemented in last commit. However, the feature is off by default, since I think it is a bit invasive. The global setting is called Display Rotation Limits.

commit 2c06345 works fine
