Email Tool: Added ability to add targets by entering the CSV in a text field

Lovely stuff, @rodrei. This looks good to me.

I'm sort of worried that if a campaigner just wants to append to the list, they will have to paste the entire list of targets (which they might not have at hand), then add theirs at the bottom.

@eyko I agree that's an issue. We could fix this by prefilling the textarea with the CSV version of the targets list (I'll try to get that in before merging).
Ideally I'd have a nicer UI using a React component using rows of textfields (one per field), and having the ability to add new rows with a "+" button. I don't think it's a big lift but I tried to comply with the ticket without spending too much extra time trying to do a fancy UI.
