Massively improved Config Key/Joy Mappings screen.

Warning is dismissable now, and cursor does not start in a position that will change a setting.
New special actions added:  ClearToDefault, ReloadFromDisk, SaveToDisk, SetListMode.  Exit is a special action.
Player is prompted to save when exiting screen instead of saving after every action.
Special actions fallback on Graphics/SMC action if they don't have their own.
Moved SMC overlay to Graphics/SMC warning.
Metrics for configuring input lock time, warning autodismiss time, lines visible, and NoSetListPrompt autodismiss time.
Header row added for cursor to start on.
ScreenMapControllers2 deleted as obsolete.
BitmapText:maxwidth changed to factor the zoom of the actor into the calculation.
