www: allow including links to NNTP sites in HTML footer

Improve the discoverability of NNTP endpoints for users
who still know what NNTP is.

==> ~/.public-inbox/config <==
; aliases for the locally-run nntpd can be specified in
; the "publicinbox" section:
[publicinbox]
	nntpserver = nntp://ou63pmih66umazou.onion/
	nntpserver = news.public-inbox.org

	; NNTPS is not supported natively, yet,
	; but one can use haproxy or similar
	; nntpserver = nntps://news.public-inbox.invalid/

; mirrors for specific inboxes may be specified either as full
; NNTP (or NNTPS) URLs, or with the server name only if the
; newsgroup name is specfied for a local NNTP server
[publicinbox "git"]
	...
	newsgroup = inbox.a.b.c
	nntpmirror = nntp://czquwvybam4bgbro.onion/
	nntpmirror = hjrcffqmbrq6wope.onion

	; there may be a mirror on a different server with a
	; different name:
	nntpmirror = nntp://news.example.com/differently.named.group

; (And I really need to write manpages for all this...)
