The firewall-turris and the related scripts were present only in Turris
3.x. This is no longer available. We can remove this safely.

It turns out that 'nb' is in no way supported by Webplate and thus
this move is pretty much removal of this translation. In the end we have
to fix our language support then.

Our current i18n system supports only nb at the moment.

I missed that feature in the last commit.

The previous version was not working with new translation files. This
fixes that and makes it also hopefully again more generic.

The primary change here is that file locations are now included in the
translation files as that can be used to navigate to the source of the
string.

The common way is that users can generate diagnostics as well as export
schnapshots in reForis but it is harder to get them once reForis is
crashing. This instead is little script that provides the same
functionality (although in not that nice coating) and works without
reForis. It covers situation when reForis does not work but Lighttpd
does and prevents need for users to go to shell to get diagnostics.

Added
* detection of binary files in `dump_file` and their dump in base64
  encoding instead of direct inclusion
* call to `hwinfo` in lshw module

Fixed
* `firmare_devices: not found` error in `firmware` module
* red herring SSL error in `turris-webs` module
* missing a module name in headers

Changed
* packages: limit updater keys we query to `/etc/updater/keys/*.pub`
  thus ignoring the `*.pub.sig` files that are also stored there.
* `Makefile` used to manage translations was improved.

This includes small hack to cover case when there is no change in po
file but due to msgmerge not updating modify time of that file the merge
is performed on every run.

This also makes sure that when update is run that it really updates all
messages not just those for change. This is intentional to make it
consistent with other repositories where update performs works
unconditionally.
