Disable Telesci's ability to summon AI

[vampirate]

Got subverted last round I played and the RD just walked over summoned me out.  He was nice enough to not kill me but that's a real bummer since it's a zero effort way to stop an AI subversion.   Not for nothing but the AI is surrounded by guns to make breaking in difficult, being able to just immediately pop in the same coordinates on any given map and shut it down is a bit much.
