Fix play_more_possible for Mole Man and Professor X

[michaeljb]

Mole Man can play up to 6 Subterranea (or whichever group he's leading if you play Advanced Solo Mode) Villains; the current implementation calculates turns based on him playing up to 6 of any Villain or Henchman card.

Note: no known interaction where it definitely affects the calculation of the turn range; if one is found, add a feature test for it and implement correctly.

Similarly, Professor X can play up to 3 Adversaries with X-Treme Attack; the current implementation calculates turns based on him playing up to 3 of any Villain or Henchman card, given Uncanny Avengers, Uncanny X-Men, or X-Men First Class are in use.

Any input on setup where these details actually affect when the Deck empties would be appreciated.
