Further work on the IRR, AC, LWS loaders. Further work on the - still unfinished - OptimizeGraph step. SceneCombiner works now properly in all cases I tested yet.

Added missing 'typename' in Colladaparser.h
First implementation of spherical and cylindrical mapping, already in use for IRR and LWO models. For the latter the coordinate system is not yet correct.
Moved vec2d to a separate header and added operators similar to vec3.
Added plane and ray helper classes. Just the data is wrapped, no operators required for the moment.
