Subject: [PATCH] Port over AI Opening Doors from Paradise

This makes an [OPEN] link appear on all radio messages the AI hears (to the right of the follow link). When clicked, it allows the AI to open
the door nearest to the speaker (or, if it is a voice changer, the door
nearest to the poor sap who had his voice stolen).

AI, Open This Door!
