Cleanup and fix missing Vimeo API methods

This cleans up and fix missing Vimeo API methods. setVolume, setMuted and stopVideo should now work.
Normalize Vimeo API methods

This cleans up and fix Vimeo API methods for setVolume and setMuted. setVolume on Vimeo is not accepting values from 0-100, but 0-1. mute() and unMute() is also not supported by Vimeo, so setMuted should be more convenient.

Thanks!
