Add random elements to map

(If TWI is already doing this and wants to give us a surprise, please delete this topic:))



Now we have random stationary machine-gun in some maps.



I hope more items can have a random position/direction, such as truck/box/road-block/resupply-site/door, so we can have a fresh experience in each round. Of course, the random is controlled by map-maker.



Furthermore, we can have random elements in a higher level, such as building/terrain/map-layout, so we can apply totally different tactics in each round. I know this need a lot of development (both programming and map-making), but maybe ten years later most FPS games will have this feature.
