[gnome-builder/wip/chergert/snippets-viewer] prefs: allow viewing snippets

commit f41305dec3c6e5c310402ea1e474154e4d8ce3b4

    prefs: allow viewing snippets
    
    This is a simple viewer for snippets registered in Builder. It does not
    currently allow for editing, due to the complexity involved with modifying
    the existing text files.
    
    That is something we'd like to do, of course.
