Fixed some typos pointed out in the comments.

Deleted 2000 lines of superfluous code and created a derpy feedback loop. By popular demand, I also added an amenities buff. It's me. I'm popular and I demanded it.

Fixed event polling for the orbital trade deposit so it no longer fires every single day. Will now only fire on planet class change. If there's anything else that removes all the deposits someone let me know and I'll look into fixing it for that too.

Whoops. Orbital trade deposit was firing every day even without a ringworld built. Should be fixed now >.<

Tweaked the description slightly
