    port-to-gtk3: Rework Gtkmm header includes (#7)
    
    Now that we are compiling against Gtkmm3 there are missing declarations
    of Gtkmm identifiers due to changes in Gtkmm internal header structure.
    
    All we have to do is bring back the declarations by including the
    appropriate headers where needed.
    
    Add necessary Gtkmm header includes.
    
    Closes #7 - Port to Gtk3
