[epiphany] Add a preference to force internal view-source

[Diego Escalante Urrelo <diegoe src gnome org>]

commit 351a6f2e63d8baf417865f108b334c9c9fd26b24
Author: Diego Escalante Urrelo <descalante igalia com>

    Add a preference to force internal view-source
    
    Using the view-source feature provided by WebKitGTK+ can be handier than
    opening gedit or the default text/html application in your system.
    This adds "internal-view-source" to org.gnome.Epiphany to force the
    internal-viewer always.
    
    Based on Ole Laursen's patch.
    
    Bug #597156
