guessed_action

new property lists all actions a player could validly do--based on the
assumptions behind best_guesses being correct
fixed bug in remove_suspicion

list comprehension wrongly recalcing based on 'perform'
added not_acting_like property

when a blockable action gets allowed, mark other players as less likely
to be the influence that could have blocked it.
changed not_acting_like to unlikely_guesses

not_acting_like changed from property to dict, mirroring
public_information

unlikely_guesses is the equivalent to best_guesses now
updated Player.___ACTION to lists

ambassador, captain now separate items.

unlikely_guesses not tested for order
