Title: osg.performance.now fallback of performance.now

Firefox 10's performance object isn't stable and is regularly reset.
An object osg.performance has been created, containing a osg.performance.now function which a bind to performance.now if present, and fallback to Date.now() if not.
osg.performance.now should be used in place of performance.now.
