Contract Improvements - v0.6.0.48

Lots of improvements with contracts. Visitors and workers have been added to possible requirements, so you can now receive (visitors) or hire (workers) as a contract. Lots of adjustments and uses of faction standing (credit rewards now depends on standing, cancel penalty amount depending on contract type). Contract stats have also been included on end game screen, and some contract info added to help.

Have also altered some window behaviour, so if you open trading from the ship comms window, when you exit, the ship comms window remains open. This makes it much easier to switch between multiple docked traders when checking prices and doing deals.

• Contract stats added (accepted/success/fail).
  
• Contract info added to help.
