UI is fixed

So I spent this morning pulling out huge chunks of the UI code that I wrote, and replacing it with something simpler. The original intention was to fudge things in favour of making the game easier to use, but that kinda backfired. So, no major screenshots or anything like that this time, but the player code seems to be a bit cleaner now.

One thing I'm noticing is that the machine seems to be pretty small, so maybe that's something to fix next?
