- Bugfix: XFileParser handles vertex colors correctly now. Fixes exception in sheep.x import 

- Added support for separate normal map filename tag in XFile material list
- shortened texture type determination in XFile loader while I was there
- Bugfix: ValidateDataStructure wrongly flagged animations with zero duration as error
