sounds at game start, between rounds/stages

[amaatouq]

Options include:

• Admin dashboard that allows the user to upload sound files to be played at the start of the game, between rounds, and between stages, and maybe at the end of the game.

• Experiment developer adds audio files to /public/games/sounds then they can specify from the admin UI the name of the file to be run for each case (i.e., round end, game start, etc)

• Have it fully in code. If so, we should provide a helper function. The best place for these sounds will be inside onGameStart onRoundStart or onRoundEnd as described here #31
