new calculations for $wage negotiation and some fixes
    minimal possible wage offer is now $1
    more more less possible overflow error for upper wages (smaller linear offset)
    not be made again offers accepted actually by NPC (and never more chaotic in the lower value of wages)
    a series (in a row) accepted reduction the offer by NPC will never lost now, (earlier lost after: "HANG UP", "HANG UP" after NPC test, "Make offer" & no crew cabin...maybe more accidental combination). If all is intended, is not really cool and logical for me.
    New, candidates hate unattractive offer (relationship -1)
    money format for "crew for hire" list
