Add live feed

Added live streaming section. Includes:
-adding a new Game model, associating that with tournament model. 
-Also added admin page for Game. 
-Add live stream to ui with chat, only shows up when one is available
-remove 'more' button from header and add 5th game image
So for every tournament we will be making a JSON request? and blocking the home page upon 5 different requests to Twitch? I do not think we can do this.
