Changes since 1.6:	+9 -6 lines
Log Message:	- tame the map/map-world.ext a bit to avoid potential memleaks for now - object refcounting was borked, fixed, again :) - add cf::attacahble::mortals_size - disable reset-after-load, this is unsafe due to locking issues, so don't do it - make map-scheduler configurable - improve emergency swap mode - prepare_random_map must be a sync job for now :( - do not keep object reference in enter_exit, the object might have been gone already. - nuke cf::object::mortals.
