The AI now has a radio channel for its private frequency.
Adds some checks to ensure the AI cannot go and speak on the radio if dead or has had its power shut down.
Code refactoring

AIs and borgs now share law statement procs, rather than have 95% identical code variants.
Improved handling available law-statement channels. Now lists all available radio channels + any additional variants (such as "Binary", "Holopad", etc.)
Fixes a bug where synths could not state laws on the binary channel due to improper return-value.
