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.

AC: A new AC test model (light + scaled texture)
IRR: Skybox, Assimp output consisting of 6 meshes and 6 textures + further test models (multi-instancing test + simple sphere and box). They are not working yet.
LWO: Test models and textures for the various mapping modes.
