Add a wait time for the rules popup (#5823)

* Create new rules popup

* Implement accept and quit buttons

* Add rules accept timer

Forces the player to read the rules by making them wait.

Speed reading the rules took me just under 45 seconds which means it'll take longer than that if someone's reading this for the first time.

* Fix info rules header

* Change _rulesPopup to local variable
