Updating to Unity 2019 & V0.4

So today I finally went to a coffee shop to get internet and download the latest version of my game engine (Unity3D). For all of Arena's development I've been using a version they put out in like January 2018. Needless to say, Unity has released a bunch of new optimizations and cool features, and I wanted them, and I wanted to download windows build support, so I updated my project. 

Overall the update went pretty smoothly! I made a new version of the Arena demo, V0.3, and posted OSX and Windows builds. I hope if works for you! And I hope you have fun :)
