Remove pause on seek

Hi Bryce,

Took me about an hour to figure it out - but there are explicit calls to Videogular's API to pause the video when a seek event occurs. 

The YouTube Javascript API sends 'player update' events when seeking - 'buffering' and then 'playing' or 'paused' depending on the original state of the player when the buffering is required. e.g. it should restart automatically.
