HTML titles and favicons

[markziemann]

I think it would be more informative and professional to have different <title> texts for the pages. Currently the majority are "DEE2", e.g.

https://dee2.io/ https://dee2.io/search https://dee2.io/stats https://dee2.io/request

Whereas the later links have more descriptive <title>s

https://dee2.io/huge/ https://dee2.io/legacy.html

There are also inconsistent favicons between the main and sub-pages. The main page has a "D", which from the source is images/favicon.svg. The other pages have "ZCB", from favicon.ico. I'm not even sure what "ZCB" is. Ziemann... something? I've attached a screenshot showing the <title> and favicon issues.
