First Unity Alpha 🎉

It's been a long while of cooking in the oven since the last update, but I know have a working Unity build of the game now. It allows for a much more readable UI and interaction than the old Python way. Not to mention it's easier for people to pick up and play with.

So changelog is... everything! This is a whole new foundation to build from and effectively a fresh start, just with similar design considerations to the old prototype. Looking forward to the next update, I'll be adding lots of tooltips and checking for new bugs cropping up.
