Title: Removed minVertexIndex Exception

This removes the exception on minVertexIndex in GraphicsDevice.DrawIndexedPrimitives().

minVertexIndex and numVertices are simply hints for software vertex processing.

Since DirectX11 and OpenGL do not support such hints these parameters are currently unused in MonoGame. We leave them only for compatibility with XNA.
