The Dashboard

The dashboard is one of the areas with the most significant area for improvement. While this project is currently Golang-based, any web development solution is acceptable--the dashboard just needs to be more responsive and usable before any sort of major release.

The dashboard should have the following features:
1. Update configuration settings, primarily SMTP host settings and server functionality (enable/disable usage to bring down server without closing) and save to dat/config/config.yml.
2. Login that checks for admin permissions. User should be redirected from the dashboard if they do not have a cookie authenticating them as an admin user.
3. Clean and accessible design
