- addRaylib just duplicates what adding raylib as dependency already does
  so it do not needs to exist
- move raygui build to standard build process when flag is enabled. this
  works correctly when using raylib as dependency and having raygui as
  dependency as well. problem with previous approach was that raygui was in
  options but it was doing nothing because you had to also use addRaygui for
  it to be effective

If we borrow from the GPU skinned animation code, we can just multiply the vertex by the matrix * weight and shave a chunk of CPU time.

Still, not fully convinced of those functions naming, despite quite descriptive, sounds a bit confusing to me...

When creating a new sphere mesh with high number of slices/rings the top and bottom parts of the generated sphere are removed. This happens because the triangles in those parts, due to high resolution, end up being very small and are removed as part of the 'par_shapes' library's optimization. Adding par_shapes_set_epsilon_degenerate_sphere(0.0); before generating the sphere mesh sets the threshold for removal of small triangles is removed and the sphere is returned to raylib correctly.
