Added a newFrame() method to UniformBindingManager

Browse Source 
to signal the beginning of a frame.  Currently this
just grabs the time and tpf values once so as to avoid
per-material Float allocation and time drift within a
frame.
RenderManager now calls this at the beginning of the
root-level render() method.
