Ports Bay's AI Radio

I saw this get PR'd in the bay coder channel.  I had to steal it.  Remie asked me to get it.
And so I did.
After six hours+ of adapting say() to use it properly since they use a (i think better?) say() code.
Anyways, features;
The AI can use all the departmental channels without having to change intercoms.  AIs can also use ;.
AI can use radio while carded.  Humans can turn the radio on/off in the intellicard interface, just like wireless.
A verb is added to the AI so they can turn the radio frequency to something different for whatever reason or if it gets EMP'd.
The radio is dependent on telecomms to function, so intercoms still have a use, as well as for ntsl.
Binary is unaffected.
