Fixes for merge

Team selection teleport.
Teleport to arena.
Gold dust chest now adds points to teams.
Teams can find how many points they have by the command "/teamscore
<teamcolor>". They can also just use "/teamscore" to see their current
team's score, or "/teamscore all" to see all the team's scores.
