+- assigns an unique ID number to the object and returns it. If an unique ID number has already been assigned to an object, then ID number is returned without reassignment
+- to just get the current ID number of an object, use sfall_func2("get_object_data", object, OBJ_DATA_ID)
+- unique ID numbers are saved in your savegame, and have a range from 0x10000000 to 0x7FFFFFFF
+- there is also an unique ID number range for the player and party members from 18000 to 83535
