Quality of life update

Hey DMs!

This is a quality of life update that allows users to expand the window to help scaling (hopefully everything will scale with it). 

I had a few people on reddit and IRL who showed me their screenshots of how small it ended up compared to their screen, and I was a bit horrified (this is what I get for using an older laptop lol). 

Anyway,  still have various buttons in the works, none have been added here to this update (my apologies, I AM working on it, I apologize!).

I've also added builds for Mac and Linux due to popular demand! I'm considering a mobile release, but that will be a LOT to work on. 

Alea Iacta Est!
