John McCardle 726a9cf09d Mobile-"ish" emscripten support
Full screen "wasm-game" for viewport compatibility between desktop and
web interfaces. Viewport modes ("fit", "center", and "stretch") should
now work the same way under WASM/SDL and SFML. This should also enable
android or web-for-mobile aspect ratios to be supported more easily.
