From 06acd2cc25db7a29a88760a120683fe10e0a63d2 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Refactor ActionContainer internals.
Make groups explicit instead of magic integer stuff.
That also makes group ordering explicit instead of magically working
(the way we happened to use it and the way unique id manager is
implemented).
