* Automate CSS-inlining for default HTML email template
The original HTML email template was added in `template/email.html`.
It looks like the CSS was manually inlined. Most likely using the
premailer.dialect.ca web form, which is mentioned in the README for
the Mailgun transactional-email-templates project. The resulting HTML
with inlined CSS was then copied into `template/default.tmpl`. This
has resulted in `email.html` and `default.tmpl` diverging at times.
This commit adds build automation to inline the CSS automatically
using [juice][1]. The Go template containing the resulting HTML has
been moved into its own file to avoid the script that performs the CSS
inlining having to parse the `default.tmpl` file to insert it there.
Fixes#1939.
