Fixed inability to download spout from maven

Spout changed the format of their repository again. @tommytony probably didn't notice because it was cached in his local maven repositoy.
Changed plugin.yml name and version information

Uses maven to get the latest name and version of the plugin.
Add permission based access to warzones

Adds a team default permission configuration option. Default is
war.player. It is modifiable at the zone level and the team level. In
autoassign zones where there is a mix of teams that some players have
access to and some that they don't, the player will only ever be placed
in a team he can access. You can't /join a team you don't have
permission to join.
