PvP updates

What I'm hoping we'll do is:

Remove the old clans pvp server completely. It's already dead and I see little hope for it at this point anyway. It will be better not to confuse players with multiple servers that essentially serve the same general purpose. Whoever happened to have bought ranks can get it back on the other server.

Conveniently, the current towny pvp server already has most of what we need, and already happens to be set up for multiworlds, so we'll generate a new map there and use that to begin work on a relaunched pvp server with the following plugin changes.

What needs to be added:

-battletracker
-playervaults (donator perk?)
-holographicdispays+patch
-update for scheduledannouncer2 (plugin is loaded, but nothing else about it works... something to look into)

Things I would also consider adding:

-populationdensity
-jobs

What we can remove:

-minigames
-warpportals (please, no portals at spawn)
-emeraldsword (too op, according to bluecharm)
-oneinthebattle (there's already another pvp stats plugin installed on the server, so not sure what else this is used for)
-randomtp (if popdensity is added, will no longer be needed)
