Added AimShout feature for holdup messages

New AimShout feature allows a quick chat message to be sent without even
moving the weapon off point of aim. While aiming, tapping the "Look
Behind" key (default is MMB) will send a customised message to local
chat. This message can be set using the command "/aimshout"

Added aimshout message to the database, removed the "vip" column.
