More renderstuff:
 - GLHelper40 is buggy/won't render. Fix that
 - Delted GLHelper20 for now, introducing GLHelperBasic as fallback
 - model file for testing purposes. Can change.
A few improvements to GLHelper40.. why you no work??
+ optimized the shader a bit if it would work
+ Replaced test.mhmd with a better version testcube.mhmd
GLHelperBasic is done. Animations not tested yet. Included is a test-
model and a testtexture.
