Continuous Deploy + misc

The main change is continuous deployment, which isn't an editor feature itself, but a dev workflow improvement. Basically you push a change and run a single command to get Github to build the downloads for you! @OPNA2608 contributed this amazing feature, thanks so much!

Additionally OPNA2608 helped get the 32-bit windows build set up! Thanks again.
