Fix player command handling in the tutorial
Move the code that checks whether a player command is a "continue tutorial" into a separate method, so that it never overrides the player command action of the active tutorial step. This could previously happen if a step had the showContinueButton flag was set to true (and a OnPlayerCommand method defined).
