Reduce CPU usage and stuttery playback

For some reason bvw_update_tags gets called constantly even when none are
changing. And each call seems to trigger a clutter scene graph update.
So totem was spending 20-25% of its time in g_signal_emit and below updating
the clutter scene graph and GTK widgets. With this fix, totem's CPU usage
drops by about a fifth and playback is much smoother (although still not
perfect).

Avoid pointless clutter scene graph updates

For some reason bvw_update_tags gets called constantly even when nothing
is changing. And each call seems to trigger a clutter scene graph update,
which seems to occupy significant real time if not CPU time.

By avoiding pointless updates, rendering is now smoother.
