[gtranslator/open-dl-button] Add the Open from Damned Lies(DL) button

[Daniel Garcia Moreno <danigm src gnome org>]

commit 0dcd9661e5fa4da07586a2a34174fd6556151876

    Add the Open from Damned Lies(DL) button
    
    A user can view two buttons in the main window when no file is opened.
    These buttons are namely: Open & Open from DL.
    
    However, if a file is opened, the user can view only the Open button.
    Thus, a user cannot load files from Damned Lies.
    
    To fix this make the Open from DL button visible when a file is opened.
    Prompt a user to save an edited file before the open button is opened.
    
    Closes #65
