love.js for LÖVE v11.3

Bringing TannerRogalsky’s amazing work on love.js up to date with the latest LÖVE release and using the latest and greatest technologies available in the form of Emscripten.

Featuring thread, coroutine, and (basic, but working on it) shader support, as well as a persistent filesystem.

All credit goes to TannerRogalsky - I just ported this to the latest version with minimal changes.

GitHub repository is available here. Live demo courtresy of MadByte can be found here.
