Major refactor

This release is a major refactor of TopoMojo v1. (And the previous repo had lot's of bulky garbage in it, so starting with a fresh repo.)

The data model change significantly; migrations will handle it, but be sure to backup your database before applying this.

Also, many of the appsettings have been renamed to streamline the configuration process. Best to review your settings thoroughly against the src/TopoMojo.Api/appsettings.conf file.
