SeruBans update, Database now checks every minute (1200 ticks) for
remote un(temp)ban/(temp)bans/warns and applies these in the live
minecraft server (and kicks if needed).

+ Some code clean up (Unneeded code, moving method call and removing
redundant (method calls, classes)), merge of the
update/untempban thread and the database maintenance thread. New
class naming for MySqlDatabase (SeruBansDatabase) and HashMap
(DatabaseCache).
