Bespoke HTML <title> string in appconfig.ini

[hyanwong]

It would be good to allow a bespoke string as a prefix for the <title> attribute in appconfig.ini. This would allow us to say "OneZoom extinct tree: XXX" for the extinct tree title, and also "OneZoom beta: XXX" for the beta tree.

I wonder if we should default to something that implies the site is running the OneZoom software, but could possibly be a copy. Then if anyone wants to run a one-zoom-like site, it's not claiming to be the original. So E.g. the default could be "OneZoom web software: XXX". What do you think @jrosindell ? We would override this with the plain "OneZoom: XXX" version for our production server
