Large-Tile Edition

As a warmup to participating in this year's 7DRL, I added a view zoom feature to ThiefRL2. Hopefully this helps people who are running on large monitors! I have a tiny little 1080p monitor here so it's not something I'd considered, but I had a request and a little bit of time so I put it in.

Unfortunately the text does not zoom, but the main game display zooms. Press 1-4 on the keyboard to set the zoom level between 1X to 4X.

Happy thiefing!
