• Add full screen toggle for Windows/Linux (on macOS, use inbuilt functionality)
• Add initial parallel printer support, not terribly useful yet
• Statically link Windows version with runtime libraries, hopefully avoiding the need to install Visual Studio runtime
• Fix config dialog ROM priority buttons
• Remove support for Visual Studio 2015 (haven't tested this for quite a while now)
• Remove support for Visual Studio 2017 (could be reinstated if anybody complains, though it'll remain unsupported)
