Added alertify for prompts on mobile side. Mobile now has a join queue button, and gets a prompt at round end to confirm that they want to play again. Next commit will rework a few things in backend to make it so that refreshing the mobile page will set the state of the join queue button properly
backend tells users when they login whether they can join the queue or not, and the button is disabled/styled appropriately. Also, logged in users can prompt a new round by joining the queue manually
user logs in and adds to queue automatically, but separately, to simplify alertify messaging. A message displays to tell them which round they will join on. A few convenience functions
initial merge of yanna's code and mine, as well as a full merge of backend into large wall
Players get prompted to rejoin the queue after each round. The queue was actually a stack, so I fixed that (I was using pop instead of shift). Players have a join queue button that they can use if they choose to not rejoin right away.
missed a line in login where it didn't return the user object and the number of rounds before that user gets to play
