Fixed a bug in the validation step - animation channels weren't validated correctly in every case.

Further work on LWO materials, writes wrap amount to UV transform property now.
NFFLoader generates spherical UV coordinates now (for spheres and all platonic solids except hexahedrons)
Importer doesn't catch exceptions in debug builds.
