JukeAlert - Modified /jamute to keep ignore lists until server restarts.

JukeAlert - Modified /jamute to keep ignore lists until server restarts.
Removed hook into the player log off event that would remove the player ignores.  With this no longer removing ignores, the ignores will remain persistent until server reboot.  Next step up will be to add to the database if folks are still finding that its non persistence is a problem.  For now, this should suffice.
