Swapped the admin panel override alert message from all players to only asay.
Fixes inconsistencies with the player panel
Every other admin window that deals with singular things (vv, traitorpanel, etc) lets you have more then one open (as long as its not about the same thing), But not pp, the central point of all of them.

This fixes that and allows you have a window open for each mob.
