the nsupdate.info zone is configured to allow updating test.nsupdate.info with a non-secret key used for the tests.
we also have a test that tries to update another host with that key and checks that this fails.
change the tests so they only use test.nsupdate.info (if possible).
single-host update secrets need a Domain record for the fqdn of this single host, the fqdn is tried first, before it tries the origin zone.
the ip address we use to send updates to is not required to be a publically available nameserver, so it is better not published.
the users of domains can query the official public nameservers from dns in the usual ways.
help: there was only a link to the rtd documentation (now directly linked from a "Documentation" navbar entry)
and some duplicate router configuration that was also shown (even with the correct values) when adding a host.
the help page html was not valid due to the values inserted into the router configuration help.
help/documentation policy: add static help to the docs, add dynamic help directly at the places (in the views) where needed

as we reference the Domain as ForeignKey in the Host, it'll kill all Hosts that reference the deleted Domain also.
needs to be the PRE_delete signal as some of the data we need is already gone when using POST.
could happen if there once was a IPv6 connection, but now is not any more.
it now kills infos older than 3 minutes from the session.
it also shows the age of the infos now on the hosts overview view (but not on home view due to cosmetic reasons).
optimization: only request the fake images for ipv4/v6 detection if we don't have a fresh IP already.
added example settings for using detectip on (ip6-)localhost
wrap host view into container div (otherwise the top headline hangs out of the screen on the left)
make ipv6 addr a bit smaller, so it might better fit on not-so-wide screens
