First signs of scavenging implemented

I've added some scavenging mechanics. There is "auto-scavenger" now, but this is a higher tier item, that player can buy in the future progres. At first, player will have to do it manually (get off the helm, stand next to the edge, and throw rope or something). Next part is GUNS!
Later I will connect everything into the system, so all the machines are working withing a reason.
The effects take a lot of time, but it's quite satisfying. Can't want till the point when I am going to start making sound for these things.
