Add [delay] action for action lists

[delay: ticks] pauses an action list, the actions below it run after the
given number of ticks on the player's scheduler. Works in menu click
actions, open/close actions, deny-actions and command rewards. If the
player leaves before that, the remaining actions are skipped and logged.

The requirements that allowed the actions (click requirements for click
actions, open requirements for open actions) are checked again after
every delay and the actions below it only run if they still pass, so a
delay can't be used to bypass them, e.g. by giving the money away before
it's taken. Action lists without a delay behave exactly as before. (6b221af)
