Fix two problems in my code as reported on Forums and in release article thread on frontpage:

* Quaternion action ipos accidently got swapped in the Ipo module
* Ipos not editable if not linked to a datablock (was possible in 2.33a)

Also fixed a typo in Object.getMatrix(): localespace -> localspace

And I add:

* channels Key 32 through Key 63 for relative vertex keys
