Improve Player controlled mob interface

[Sam Guivene]

I recall hearing in the past that, to a significant extent, players controlling NPC mobs is bugged to hell, in some cases entirely unplayable, and in others just extremely convoluted or annoying to do, causing issues with many things such as many admin martian diplomat events and such. I suggest we revamp this system, not only for the sake of admin gimmicks, but so that it could open a whole new window into player, antagonist, NPC, deathspawn, whatever interaction, and in doing so could potentially open up a myriad of options for the future. Also arguably the lack of potential player mob interface is arguably a bug to begin with so why not.
