Playground additions

[jampeh]

I have been loving making playgrounds and viewing other player's playgrounds. I had this idea to try to make a fun roguelike game mode. It is possible to make one right now but only for single-player. For multiplayer to work players would need to have a teleport all gizmo/gadget, along with something like on player death all players die. Maybe even a reset playground gizmo on player death.
