WebGL build

[HuangJunye]

I am planning to make a WebGL build for people to play on itch.io @boland25 already make QPong service on IBM cloud and I rescale everything down. I think I should be able to just make the build to play on browser.

The QPong service suffers some lag which affects gameplay significantly. In the long run, making a C# qiskit is probably the way to go. See issue #54

It is probably a good idea to launch it at the same time as Qiskit Camp Europe. People can play even if they are not participating physically at Qiskit Camp.
