Subject: * Changes to map_foreach* functions: - removed the unecessary use of
 va_copy in map_foreachpc - applied the same function pattern to
 map_foreachmob and map_foreachiddb - created map_foreachnpc - extended the
 behaviour of map_foreach* functions to stop iterating when func returns -1
 (also added missing changelog entries from ultramage >.>)
