Cleanup of MotionPaths+Ghosts (AnimViz) - Part 1

This commit sets up some of the groundwork necessary to extend the animation visualisation capabilities, previously only available for bones in PoseMode, to Objects as well. Also, some of the other goals of this refactor is to make future visualisation goodies (i.e. editable paths) more feasible...
(There's really nothing to see here yet. The following log notes are really just for my own reference to keep track of things.)

Currently, the following things have been done:
* New datastructures + settings have been tidied up, ready for usage
* Added these new types into the Object and PoseBone code as necessary, with freeing/adding/copying accounted for
* File IO code for the new data, including version patching to convert the old system to the new one.
* Set up the drawing system for motionpaths based on the old armature path drawing code. Armatures still draw using the old system, since the two systems use different storage systems.
* Started setting up the motionpath 'baking' code, but the core of this still needs to be coded...

Next Steps (after some semi-urgent Durian Driver changes):
* Port the ghosting/onionskinning code over too
* Finish motionpath baking code
* RNA wrapping for the new types
* Hooking up all the new code into the operators, etc.
