Can we have "Copy to Clipboard" button on the install page?

[okuramasafumi]

Summary

On https://www.rust-lang.org/tools/install I'd like to have "Copy to Clipboard" button on the install code.

Motivation

While copy and paste is still possible without the button, I think putting "Copy to Clipboard" button makes it even easier to prevent mistakes.

Drawbacks

We need some amount of JavaScript.

Rationale and alternatives

Maintenance

Only a few lines of JavaScript should not be hard to maintain, but some browsers might not support it yet.

I think it would be a nice and simple addition. I will try to implement it.

What "copy-to-clipboard"-svg should I use. I'm not familiar with the licenses in this case.
