Initial Release

Works on Linux and Windows. macOS untested.

Usage instructions:

• Windows: run SS14.Launcher.exe
• Linux: run SS14.Launcher. It's a native Linux executable this time so no Mono needed.
• macOS: Pretty sure Finder isn't gonna let you run native binaries directly so run SS14.Launcher from a terminal.

The releases are huge because they use self contained .NET Core. Made it a hell of a lot easier to write.
