Remove time limit for the first move for non-tourney games

[visualdenniss]

In Lichess there is no time limit for the first move when one is playing against AI or simply playing from lobby/challenge. Basically only in tournament play there is a time restriction for the first move. This applies to both registered users and also anon users (e.g. when they play against AI), so i d suggest implementing this practice to pychess as well, as one in some variants either needs to think more on first move, or move when ready in a match play or simply need to talk to his opponents before the game etc.
