Just a small patch to fix a couple of bugs that were pointed out to me from the last release!

***fixes***
.Autosaves on leaving a station or trader screen would crash on load (thanks enfilade!).
.Resetting the game and making a clean save would crash the game.
.Holding down B for too long on entering a station or trade screen would kick you back out into the world. The game now checks for you releasing B first.
