appDisplay: Use AppFolderDialog grabHelper to obtain key focus on popup()

When an app folder is opened it would do so without grabbing the
keyboard focus, so one could not navigate with the arrow keys without
pressing Tab. This adds the focus parameter to popup()'s grab, which
sets the key focus to the elements of the folder when it is opened.
