(7dc4f5c23) Fix the doors: - Don't allow to pick, if the doors has no requirments. In this case the door should be opened by using the [select] key. - Display "UNAUTHORIZED ACCESS" when the door has integrated buttons but the requirements are not met. Display the cannot open the door text when the door doesn't have integrated buttons and the player is trying to open the door with the [select] key.
