Add footer
The motivation is to display "Powered by ...". The patch I received adds
that text to header, and I felt it stands out too much considering
frequency of user using (reading and getting actually useful
information from) it. I like the idea of "Powered by" as there were
times that text helped me discover new tools.
The most natural place to put it is footer, but my legit fork does not
have that. And just having "Powered by ..." text alone feels off, so I
added admin configurable links section for things like contact email
address, mirrors, and other social links.
I personally like the outcome.
