Improve starter Scav crew trait weights

[resistor]

Starter crew for Scavengers don't seem to have many weighted traits useful for Salvaging. I suggest replacing some of their irrelevant weighted traits like Neverlost with more relevant ones like Problem Solver, Mechsync (for dice that helps with reward factors), or Crafty (for bonus Salvage cargo).

Interesting feedback. They do have a whole set of special Traits picked out for them in new game. Sorry that you don't like their set. I've added it to the long list to take another look.
