Make self-hosting on Windows easy

Most users do not use Linux. It is a shame, but it is true. It is desirable to make it as easy as possible to run this application on the most popular operating system for users around the world, and that operating system is Windows. This will make the tool available to not only computer programmers and general IT people, but some ordinary users too.

The Windows self-hosted package should have the following qualities.

1. Able to be installed with a `.msi` installer.
2. Bundling of Postgres server in Docker image with automatically generated secure, but accessible, password.
3. Exporting and importing of Postgres database with a simple interface so regular users can create backups.
4. Some capacity of Windows Server support for those who have a Windows Server OS installed.
5. Ease of access and configuration for SMTP settings for email delivery.
6. A "test email" tool for testing email delivery.
7. Ease of configuration of hosted port number and address.
8. Integration with Windows Task Scheduler as a substitute for cron.
9. Ability to function on systems that are shut down over night, such as a desktop.
10. System tray integration for Windows desktops.
