Another week another update! Really getting close to simply locking this down!

-Balance changes for Hard Difficulty level to make more difficult.
-Reward amounts balancing for all difficulty levels
-Stores now have credits which means you can't sell unlimited amounts of goods for an unlimited amount of credits.
-High score leader boards are now only reported and saved for Medium and Hard difficulty.
-Blockades will no longer show up on 2 planets in a row.
-Fix for alerts to crewman/ship deaths during hyperspace travel.
