Add multi-round functionality

[WhiteJP]

Add multiple round functionality. First just with the same map, then adding in the different maps of different universalizability. Plan is to have 3 "learn" rounds and one "test" round.

• [x] multi rounds with same map
• [x] fix bugs with initializing and with scores
• [x] multi rounds with diff maps
• [x] add in treatments for conditions
• [x] For more than 2 players (maybe start with options for 2, 4 and 8)
• [x] add total score to profile instead of page
• [x] fix total score bug
• [x] enable random order of maps in learn rounds
• [x] Make sensible start positions for each map (for now)

Added logic to set different maps, starting positions on them (which are permuted), and to send to phaser game to load: 398aa2461f787dd69b500b16f7585cb16478d8af

Now just to try with the real maps :)

Now done with real maps :)

Reopen issue as there is still a bug with the total score. It seems like it is adding the round score twice somehwere in the logic, or that it adds an extra 1 each round.
