Fixed 3DS, ASE, MD3 and Q3D orientation after Schrompf' recent changes to the RH-LH conversion.

WIP version of animation support in the 3DS loader. Still hoping to find out why the pivots aren't handled correctly ...
Added first draft of a B3D loader provided by Mark Sibly.
Moved DeterminePType-Step to ScenePreprocessor.
Small LWO fix. Still texturing problems.
