2.5 PoseLib - First steps to get PoseLib to work in 2.5

* Cleaned up Keyframing API to get eliminate some of the problems faced during the original implementation of PoseLib, thus reducing code redundancy. 
* Added new Animato evaluation functions specifically for use by PoseLib. 
* Replaced parts of PoseLib code which relied on old animation system to the equivalent code for Animato. Notice the much cleaner + saner + compact code!

Next step is to operatorfy the PoseLib tools (while maintaining possibility for an API to some things) :)
