Customizable/alternative colour schemes

[tgraham-antenna]

I use two eXist-db instances: one for writing code and one for testing deployment.

So that I don't confuse the two, I've resorted to changing the dashboard CSS for one of them so that its dashboard has a different background colour.

It seems to me that it could be useful if the dashboard supported predefined alternative colour schemes, as a minimum, so that it's simple to differentiate the dashboards of different eXist instances.

Sounds nice. It would also seem a good idea to me if it prominently displayed the hostname or data directory location.
