Preliminary macOS support

consider this release as a beta build for macOS support, it isn't tested super well but it does work. instead of installing JVM's in the app and running them in process, it simply uses JVM's installed on your Mac already. There's no reason to use this over just running the java -jar [minecraft server jar].jar command in your terminal other than just providing a nice GUI. should have feature parity with the TrollStore version for iOS.

the app is not notarized, so you'll have to manually trust it in settings
