        Schemas to maintain compatibility with the 2.0/2.2
        configurations.

        The problem being addressed here is that because the
        2.0/2.2 panel applies schemas to keys at runtime,
        existing user configurations will end up with
        dangling references to the old schemas unless we
        install these old schemas.

        For example, a 2.0/2.2 panel will apply the
        medium/general/panel_id_list schema to
        profiles/default/general/panel_id_list. This
        association is in the user's configuration, not in
        the system GConf database. If the user never changes
        panel_id_list and logs into a machine without this
        schema, then panel_id_list will be empty.

        * panel-compatibility.schemas: re-add the old
        default config schemas.

        * Makefile.am: install the schemas.
