Add "todo edit --description" for comfy editing in external editor

[hut]

My primary use case of todoman is comfortable editing of descriptions of tasks in a separate editor. The reason is that most data of a task is simple enough to be editable via low-bandwidth interfaces like android clients or thunderbird/lightning. But the description may contain a long text, so the use of a dedicated text editor is warranted.

Currently the same thing can be achieved by running todo edit <taskid>, pressing the arrow key down, then pressing <C-O>. With the option from this PR, all you need is to pass the --description option to the edit command to open the item directly in the editor.

Feel free to change the name of the option. Related issue: #292

I'm not sure what I should do (or whether i should do anything) about codecov check failure.

Thanks, this looks pretty good. --description sounds slightly odd, but I can't think of anything better, so it's fine by me (@untitaker, any comments?).

Can you please add some tests for that cover this new feature?
Also, please add yourself to AUTHORS and include a CHANGELOG entry (this'd be v3.5.0)

Again, thanks!

This is inconsistent with `todo new` which has an option for reading the description from stdin. Not entirely sure what's better but I think we should standardize on this.

Is there some recommended way to use todo new --read-description combined with a text editor?

[untitaker]

You can use -i. There is a shortcut to open $EDITOR for the currently focused textfield in the interactive UI Or you write a wrapper script

I guess it's best to add an option that reads from stdin. While using the text editor directly is probably the most common use case... Once you got another use case, you'd be out of luck.

Q1: The user would be left to implement tons of boilerplate though, reading the info from stdin, calling the editor, etc. Maybe we should provide a wrapper script, if we do it this way?

Q2: I can't find a way to easily fetch the description of a task. todo --porcelain show <taskid> doesn't show it either. It wouldn't break anything if I add the description there, right?

[WhyNotHugo]

I won't break anything, adding to --portecelain is fine, the only restriction is to avoid deleting or changing stuff there.
