Disables mouse and keyboard controls. Disabling the input in Camelot is managed as an integer. It means that each time DisableInput succeeds, it disables the input once, and EnableInput must called as many times as DisableInput was called to actually enable the player input.
Pressing the escape button disables the input and pressing it again enables it.
Certain actions including ShowList, ShowCredits, ShowNarration, ShowList, and ShowDialog also enable the input since they are normally followed by a corresponding Show action, e.g. HideDialog, and those actions disable the input.
