Add choice of video resolutions for instance owner

Browse Source 
The instance owner can choose from the list of available resolutions.
['144p', '240p', '360p', '480p', '720p', '1080p']
Also, the default resolution is now set to 480p and the instance owner
can choose the default resolution from that list as well.
