    shortcut-editor: use a different page to edit custom shortcuts
    
    When adding a new keyboard shortcut, in accordance to the mockups,
    the dialog should present a new page calling for an action from the
    user.
    
    This patch adds this page, and adapts the code to show it whenever
    the user wants to change the shortcut.
