Add more interesting things to find around the map in freeplay

[jotun]

One of the fun things about the old demo, after completing the objectives, was to go find all the ship wreckage that was scattered around the map, and get the goodies inside. It would be cool if freeplay had neat things like that to find while exploring. Maybe some ship wreckage, partially-destroyed old bases, etc

+1 for randomly scattered loot crates on the map! :)
