Couple of fixes

Fixed #12 and #13

Some comments on what I've seen thus far. The commit history is a little bit messy - in the future I'd recommend self-contained, atomic commits, ideally with messages that describe what and why something has been done.

It's fine by me to add a copyright note, but it's less fine to sneak it in a "bugfix" commit. Commit messages should ideally reflect all the changes made, even if they're "bureaucrat" ones.

However, at this point I'd like to defer to @wenkesj as to whether he's fine with this addition, as I don't feel comfortable merging this in.

Sorry about that. Doesn't have to be there if you don't like it.

If the player folds, the self._current_player is not moved on (self._current_player = self._next(players, self._current_player)). So the same player is again asked for an action, which again is fold, and now when it tries to remove the player there's a ValueError as the player was already removed (see trace below).

The player needs to be moved on before removing from players:

      if move[0] == 'fold':
        self._current_player.playing_hand = False
        folded_player = self._current_player
        self._current_player = self._next(players, self._current_player)
        players.remove(folded_player)
        self._folded_players.append(folded_player)
      else:      
        self._current_player = self._next(players, self._current_player)

total pot: 39460
last action by player 3:
x fold

@BigBadBurrow I suspect you are not resetting the environment after getting done==True

@BigBadBurrow can you test if my fork works with your setup?
