Third and last commit for Brecht's IK work.

Full logs for changes will be added later. Worth to note now;
- support for 'tree IK' added
- DOF and stiffness per IK bone (in pose only)
- Orientation IK support (target rotates -> chain follows)

This is still WIP. Buttons might change, button ranges will change, and the
way 'IK groups' are working will change. You can play with this, but don't
expect saved files to work still by end of this day! :)
