HMP loader returns quads now, cleaned up the code a bit. Still longer than necessary.

BVH loader supports arbitrary rotation/translation orders now. Fixed a crash issue, added test models with ZYX and ZXY rotation order.
Updated CREDITS.
'Beautified' pushpack/poppack.
Collada loader does now also load XML files if 'COLLADA' is found in the header.
Fixed path issues in several IRR test files.
