port to emscripten

[aashidham]

Can you alter the build toolset to target emscripten? The website has some comments about how to do this (https://kripken.github.io/emscripten-site/docs/compiling/Building-Projects.html), and I think it would help the project and the community to add this as a target. I am willing to pay a developer for this feature request to be implemented in a timely manner.
