#17 Please add quadric models (videoGLU)

[Wolfgang Scherr]

I attached ported code from the MESA library and added a ZIP file containing videoGLU.h and videoGLU.c:

Following functions are defined, more or less "OpenGL"
compatible:

gluNewQuadric()
gluCylinder(), gluPartialDisk(), gluDisk(), gluSphere()

This adds basic 3D models to the libnds library.

addional glu3DAxis() draw simple x/y/z axis

They may not be of highest performance up to now, but normal generation etc. work IMHO correctly (no clipping at +1.0 etc.). All except texture mapping is tested using some examples.
