    ephy-location-controller: Add longpress to select url text
    
    Currently a touch screen user has no easy option to mark the whole url text for deleting as it is 
provided by other touch based system.
    
    Adding a long press gesture to ephy-location-controller fixes the issues and allows quick and easy page 
switching.
