Added lockscreen trapping and media pausing for lockscreen. When it is invoked `lockscreen`, all media will be attempted to be pause and the system will be muted. Then the lockscreen is engaged. This should happen automatically when the screen shuts off or the system suspends or hibernates and can be invoked manually, as before, with super+x shortcut.
