Add "Copy Unproxied URL" context-menu option

[dstillman]

In the save button context menu (inverse of Reload via Proxy) and the link context menu, for recognized proxy URLs.

The latter would help for stupidly proxied doi.org URLs, as in https://fediscience.org/@adam42smith/109742230235324956

This isn't working for me in Chrome. I go to JSTOR, right-click on a proxied link, choose "Copy unproxied link", and my clipboard still has old data on it.

Did you get a prompt to authorize the extension for clipboard access?

Nope
