added base texture class, untested (and used)so far
changed the order of imports and methods
added: Polygon-class and TexturedPolygon
added main.py, and created a test class there. included glut.dll.
the test now works, but there's atleast a bug in loading the texture
fixed the loading bug, but the texture is now wrong size (stretched wrong?)
changed the test_texture, fixes, fixes everywhere!
Merge pull request #5 from Tyyppi77/master
