Don't show copied text if its hash is in a list configured by the user

[wtobi]

I don't want passwords to be visible in pano. There are several great ways to prevent this, but there's one thing that's apparently not covered: Copying passwords from 1Password's browser extension.

For me, it's only one password that I need to copy regularly. So it would be totally sufficient for me to be able to add the hash of this password to a list of excluded hashes.

Copying the password from the 1Password desktop app instead of the browser extension works, but requires me to open an extra app.
Letting the browser extension set a mime type that prevents the password from showing would also work.
