Here is the big, bad function that broadcasts a message given the appropriate parameters.
@param M: Reference to the mob/speaker, stored in signal.data["mob"]
@param vmask: Boolean value if the mob is "hiding" its identity via voice mask, stored in signal.data["vmask"]
@param vmessage: If specified, will display this as the message; such as "chimpering" for monkeys if the mob is not understood. Stored in signal.data["vmessage"].
@param radio: Reference to the radio broadcasting the message, stored in signal.data["radio"]
@param message: The actual string message to display to mobs who understood mob M. Stored in signal.data["message"]
@param name: The name to display when a mob receives the message. signal.data["name"]
@param job: The name job to display for the AI when it receives the message. signal.data["job"]
@param realname: The "real" name associated with the mob. signal.data["realname"]
@param vname: If specified, will use this name when mob M is not understood. signal.data["vname"]
@param data: If specified: 1 -- Will only broadcast to intercoms 2 -- Will only broadcast to intercoms and station-bounced radios 3 -- Broadcast to syndicate frequency 4 -- AI can't track down this person. Useful for imitation broadcasts where you can't find the actual mob
@param compression: If 0, the signal is audible If nonzero, the signal may be partially inaudible or just complete gibberish.
@param level: The list of Z levels that the sending radio is broadcasting to. Having 0 in the list broadcasts on all levels
