    application, base-model: Handle app.search-* more globally
    
    So far, only the BaseModels used by Dropdown used the app.search-*
    GActions to change the active SearchMatch, SearchType and Source used
    by SEARCH. Going forward, they are also going to be used to select the
    attached device from which to import. Therefore, it makes sense to
    handle their state changes in a more global location than BaseModel.
