Feature Request: display the database name on the main page

[tfrazee]

In our environment, we run multiple races over the course of a couple of days. Currently I am switching between multiple databases instead of multiple instances of derbynet.

It would be valuable to display the name of the database across the top part of the page for the main menu OR every page. Being able to enable or disable this feature from the setup page would reduce clutter for users who use 1 database for everything.
