Add comment about how a hack also fixes bug 5799.

        * components/services/install/lib/eazel-install-logic2.c:
        (check_conflicts_against_already_installed_packages):

        Add comment about how a hack also fixes bug 5799.

        * components/services/install/lib/eazel-install-xml-package-list.c:
        (osd_parse_softpkg):

        Parse REVISION tag in softcat XML for the install lib.

        * components/services/install/nautilus-view/nautilus-service-instal
        l-view.c: (generate_install_form), (show_overall_feedback),
        (nautilus_install_parse_uri), (current_progress_bar_complete),
        (nautilus_service_install_downloading),
        (nautilus_service_install_dependency_check),
        (flatten_package_tree_foreach), (flatten_package_tree),
        (nautilus_service_install_preflight_check),
        (nautilus_service_install_view_update_from_uri):

        Re-layout a little bit of the top of the install view, to make the
        overall feedback label not flicker.  Remove some redundant redraws
        that had been stuck in to work around the NautilusLabel redraw
        sizing bug.  Sneak in support for multiple packages in the eazel-
        install URI scheme.  Remove repeating package names from the final
        list during preflight.  Give some overall feedback during package
        dependency checking so the user doesn't think we're lost in space.
