macOS Support

Per the release of Mojave (10.14) I’ve upgraded my development hardware and am focused on cross-platform SDL support for macOS. There are a few known bugs with the current release of SDL2 (2.0.8) that are being addressed. Once those fixes make it into a stable release will push out v4.1.1. This release will also include some minor bug fixes to the Objeck compiler for example allowing “break” statements in nested loops.
