appview: introduce email notifications for @ mentions on issue/pr comments #393

closed
opened by boltless.me targeting master from boltless.me/core: feat/mentions

Stacked on top of #392

Yes, I know we have stacked PRs, but I want to explicitly separate two sets of commits and review both on different places

This is MVC implementation of email notification.

Still lot of parts are missing, but this is a PR with most basic features.
