Allow creating attachment from textinput (like copy-paste)

[neufeind]

Summary

It would be great to be able to attach certain things (like for example a key) from a text-input and not just by selecting a file. Currently you have to copy-paste into a file first, import that as an attachment and can remove the external file again afterwards.

Examples

Maybe have a button "New" next to "Add" (which currently adds a file)?

Context

I wanted to add ssh-keys from another source, through copy-paste. I had to create files first to be able to attach them to an entry.
