Draw gtk_cat columns on initialiation in .gui() call. Use more literal uikit.do() invocations without lambda: wrapping. Let display_categories only run in uikit.do/idle, whereas .load() is run directly from there now. check-in: f1a357a60d user: mario tags: trunk

Make uikit.do() manage a task spool itself. Run new tasks immediately if invoked already within gtk_idle callback. Move uikit.tree column creation into separate function, for immediate use through GenericChannel.gui() - instead of destroying+repopulating it on category-list reloads. check-in: 7f51022370 user: mario tags: trunk
