3.0.3 "Hacky-Slashy New Year!"

This SquidSetup release coincides with SquidLib 3.0.3's release today; it updates libGDX to 1.9.12 and includes various improvements from gdx-liftoff. I'm not 100% sure all of the platforms work as they should, but LWJGL3, HTML, and Android have been tested and the generated projects run. This release returns to using GWT 2.9.0 by default with a custom GWT backend for libGDX, which allows using up to Java language level 11 for GWT projects (but not all of Java 11's standard library). The assets are mostly the same, but do now include Cascadia Mono as an MSDF font, which is very nice.
