Merge branch 'spectate_mode_basic' into 'master'

Spectate mode basic

Client can now select spectate when connecting to a race.
- The "Join game" button has been split into "Participate" and "Spectate".
- Selecting spectate should join the game, but not assign a boat.
- Spectator cannot control any boats, or have an effect on game.
- Can spectate a game even if it is full.
