Pole Target for IK

Browse Source 
==================

This adds an extra target to the IK solver constraint to define the
roll of the IK chain.

http://www.blender.org/development/current-projects/changes-since-244/inverse-kinematics/

Also fixes a crashes using ctrl+I to set an IK constraint on a bone
due to the recent constraints refactor.
