Idea: Show PKCS#11 URL in GUI

[harrison314]

It might be good to give crypto objects the ability to show or copy the PKCS#11 URL.

Specification: https://www.rfc-editor.org/rfc/rfc7512.html

It is necessary to:

1. Check whether it is possible to implement such a feature.
2. Find out how to display the given URL (for example, on an object, or just a copy button, or will a form be needed in a dialog window).
3. Decide whether this feature has usability in its current form.
