Matrix decomposition in use

No need to pass separate translations and rotations around.
Blender Collada export support.

Still few bugs persist.
Collada parser, JointFrame getTime function.

Makes the code a bit cleaner.
Deleted redundant checks from COLLADA parsing.
Restructured Collada parser.

Moved parsing of library_visual_scenes node from collada.(hc)pp
to collada_library_visual_scene.(hc)pp.

Also moved everything collada related to animation/collada dir.
Box uses now 8 points instead of edges. Box as floor complete. To-do: box rotation?
