changed order of gamesetup command aliasing (conflicts between aliases caused loading bugs when using @adddamage and @addbehavior)
added basic regions functionality (ported and heavily modified from Cortex Engine) and created engine/ui_helper.galaxy for ui dialogs:
- added region management commands #create, #remove, and #list
- added region waygate functionality (allows units to teleport between regions)

region waygate related events have been added to events/region_waygates.galaxy.
