Add "resolution" field to task upon checking done

[gmkado]

Perhaps related to #665 and #526

I often want to add a resolution description after completing a task. Just one line of text would work for most cases (e.g. url to a pull request, "won't do because...", etc)

I'm imagining a button like the edit and link buttons that would pop up a modal. When you enter in the resolution and press ok, it adds the resolution text and checks the checkbox.

Thank you for the idea. The current work around is to add this additional data to your task in markdown. It is less convenient, of course, as you cannot do it when completing a task from a query.

Yeah thats what I currently do and its not a bad workaround, I just want all the things 😄
Thanks for the great plugin!
