Corrected documentation of ImmutableVector3 and made
Vector3#getAxisVector(Axis) throw an IllegalArgumentException rather
than return null on invalid input.
Refactored some methods from Quaternion into Vector3. Fixed a perceived
error in the vector to vector projection method.

Merge pull request #974 from MasDennis/OpenGL_ES_3

Adds initial support for OpenGL ES 3.0
Fixed issue with orientation. The ImmutableVector3 implimentation was
not behaving as expected. Returned to a mutable Vector3 for the X,Y,Z
axis vectors and warned developers to not modify. This is a tradeoff of
safety for speed and since no one should ever mess with those vectors,
this has been deemed acceptable by myself and @ToxicBakery.

Fixed UV order in Sphere

The order of U was backwards and was set as negative to fix. It is now
properly reversed.
