Log Message:	hell on earth, rewrote the container code - it really was a mess before - open/close events should now be very reliable. - make container an object_ptr, just to be on the safe side (the old code is known to crash, the new code should be reliable, but...). - its also smaller, much smaller/clearer in sourcecode size and a bit smaller in text segment size. also disable big worldmap again: is this still causing memleaks?
