They don't share a common ancestor type so they were relying on the
secbot having identical vars to the ed209, this is brittle and ugly, so
instead a bitflag of criteria is passed through the mob assess_threat
proc so it can choose how to react to each criteria
As well as that, the weaponscheck proc used by the bots is now passed
through as a callback, more things can now implement their own
weapons checking for threat assessment if they need
This means more things can now utilise the assess_threat proc if they so
wanted to, as they no longer need to map 1 -> 1 to the ed209's vars
Also fixed a runtime where the secbot didn't pass through itself to the
assess_threat proc (what I originally wanted to fix)
