Merge branch 'english_notify' of https://github.com/oskar456/turris-misc into oskar456-english_notify

Signed-off-by: Ondřej Caletka <ondrej@caletka.cz>

Recreate the gpg home directory instead of packing it in git. It seems
the format is not transferable.

Also, provide maintenance script to refresh the keys (import
revocations, etc).

And move the directory to .git-gpg, so it doesn't bother people.

To check the tip of the current git branch is signed.

If unbound is not installed or is disabled, don't even examine it if
it's running.

Add a configuration option to forbid some services from being restarted
by the watchdog.

I don't know the coding style, but the majority of file uses tabs, so I
retabbed everything.

This adds router host name into the subject of e-mail notification,
which is useful if someone has more than one Turris router.

Gets data from database to feed it.

Script to feed honeypot sessions into a public map.

Accept single language as well as both. But warn in such case.

Also, detect language of mail to send.

We added a parameter, so we need to add one to the checked number.

The space is explicitly forbidden as part of encoded text by RFC 2047,
the encoding must be broken out of and re-entered as needed.

Make sure the script fails when something can't be downloaded. Also make
sure the old file is not overwritten in such case.

Store just one certificate (the new one), since nikola can not handle
multi-certificate files.

Store the correct one ‒ we had two copies of the old one previously.
