11.4 web build now supported by min-love2d-fennel

[alexjgriffith]

For those developing on linux with Fennel, the Minimal LOVE2D Fennel setup now defaults to 11.4. This includes the web release, with the emscripten patch ported over from @Davidobots 11.3 version.

The project still ships with the 11.3 web target embedded, in case there are any unforeseen regressions.
