* Make generate-schemas output GConf or GSettings XML, or a text dump,
  according to an option flag.

* Default is still to use GConf as many systems don't have the necessary
  file backed GSettingsBackends installed:

    GLib-GIO-Message: Using the 'memory' GSettings backend.  Your
    settings will not be saved or shared with other applications.

* Split GnomeSettingsStore.cpp into GSettingsStore.cpp, GConfStore.cpp and
  NoStore.cpp and compile conditionally.

* As the "Actions" box is gone (0f139f46), comment out all action code with
  #ifdef XXXPRLWACTIONSAREFIXED, and remove action specific source files
  from build.
  Actions were the only consumers of dasher_app_settings_{g,s}et_free_long.

* Removed GConf NotificationCallback as all it did was return.

* g/c another reference to an "intl" directory.
