Add CLUTTER_VBLANK=none to fix certain graphics card related issues

Some graphics drivers like the intel one have problems with redrawing
when using clutter-gtk. Using CLUTTER_VBLANK=none it works again.
Since other graphics card configurations do no show any disadvantages
we set CLUTTER_VBLANK=none as default. Setting CLUTTER_VBLANK manually
will still override the default 'none' setting.
