Add an "evolution:button_label" property on the component for use in the
* gui/component/GNOME_Evolution_Addressbook.server.in.in: Add an "evolution:button_label" property on the component for use in the shell. * gui/GNOME_Evolution_Calendar.server.in.in: Add an "evolution:button_label" property on the component for use in the shell. * GNOME_Evolution_Mail.server.in.in: Add an "evolution:button_label" attribute to the Component for use in the shell. * e-shell-window.c (struct _ComponentView): New member button_id. (struct _EShellWindowPrivate): New member sidebar. (component_new_new): Get a button_id arg. (component_button_clicked_callback): Removed. (sidebar_button_selected_callback): New. (create_component_button): Removed. (setup_widget): Set up the sidebar using ESidebar and hook up its "button_selected" signal. Also get the component name from a property on the server info. (e_shell_window_new): Use BASE_VERSION for the version in the app name instead of hardcoding "1.5". * e-sidebar.c: New. * e-sidebar.h: New. svn path=/trunk/; revision=22988
