Console Cooldown Tweaks

-Cooldown for sending messages to centcom reduced to a minute. Often times conversations between the messenger and centcom are cut short by the very long cooldown time.
-Cooldown for AI priority announcements increased to 5 minutes. The fear I had when I implemented it was AIs misusing it by announcing pointless things for what should be reserved for actual important things.
-Ferry move request cooldown increased to a minute. Stop spamming us admins please.
-Reverted AI announcement cooldown change
-AI announcements are now minor announcements
