Keying Set Fixes:

* 'Export Keying Set' operator works again - a change in the previous commit broke the created code
* Relative Keying Sets don't get their paths shown 
* Keying Set paths show options for inserting keyframes too now

---

Another attempt at fixing compile troubles, and removed some commented out + obsolete stuff.
