Bug 1304134. Part 1 - per spec. (https://dev.w3.org/html5/spec-preview/media-elements.html#ready-states) 'playing' should be fired before activating autoplay. r=cpearce

Browse Source 
Also replace the check for IsPotentiallyPlaying() with !mPaused because mReadyState >= HAVE_FUTURE_DATA guarantees playback is not ended.
