Branch:	MAIN
Changes since 1.38:	+1 -1 lines
Log Message:	VERY EXPERIMENTAL - change the way archetypes and treasurelists are being loaded: - referring to a nonexisting treasurelist will create an empty one - referring to a nonexisting archetype will create an empty one - archetypes/treasurelists will overwrite any existing object of the same name. - net effect should be to allow reloading of archetypes and treasurelists at runtime at a later stage.
