- start-game
- swap-players
- end-game

compojure handlers made more spiffy, they can generate errors based on
missing arguments.

logic is ALL MOCKED, need db code.
- Added simple login page... need to add session + redirection
- Shows access token when allowing google+ access...  this token will be sent to backend for further verification
add get-users and update-user api endpoints
s/permissions/roles/
- Added login page... still needs to handle session and communication with backend + redirection
