Deprecate stdweb and migrate to web-sys

[ryanisaacg]

Rationale: Unfortunately, stdweb has been going unmaintained (as has its sister project, cargo-web.) web-sys and wasm-bindgen have more than reached parity with stdweb, and progress on tooling to match cargo-web is going well. Contributions to upstream projects like winit are increasingly web-sys only, so the pressure is there to remove stdweb support.

To make web-sys the default or remove stdweb entirely, we need to:

• [ ] Document a new workflow (#652)
• [ ] Add a warning when compiling under stdweb
• [ ] Document any issues this causes (in this issue)
• [ ] Contribute a stdweb to web-sys transition to gilrs

Please feel free to reply with any issues you encounter with moving to web-sys for Quicksilver projects.

👍 I've stopped maintaining stdweb in https://github.com/johnpmayer/quicksilver-utils

I have a not-too-large, but complete and documented example that should run with web-sys.

FWIW, I was able to get quicksilver 0.3 compiling with wasm-bindgen/wasm-pack, I just needed to add a patch section to Cargo.toml for stdweb to this branch.
