Game Rules: Update to the controllers section

[Zanz]

I'm fine with that formulation, though I suggest "Will" instead of "Can", at least for the 2 month timespan - I think after 2 months inactivity the mods should be pruning players actively, it should not be a passive "well we'll do it if there's a request" - Primaries should be ended if a player has not done anything there for 2 months.
