Subject: [PATCH] webmail: add buttons to download a message as eml, and export
1 or more messages as mbox/maildir in zip/tgz/tar, like for entire mailboxes
Download as eml is useful with firefox, because opening the raw message in a
new tab, and then downloading it, causes firefox to request the url without
cookies, causing it to save a "403 - forbidden" response.
Exporting a selection is useful during all kinds of testing. Makes it easy to
an entire thread, or just some messages.
The export popover now has buttons for each combination of mbox/maildir vs
zip/tgz/tar. Before you may have had to select the email format and archive
format first, followed by a click. Now it's just a click.
