additional german translation

We did the same sanity cleanup for all other code.  Easier on the
eyes and easier to fork.  ;)

Discussed with: ad@

when a conditional is the last stament on the line, either make sure there's an extra new line or add some characters behind it.
"trim_blocks" is removing this new line otherwise (http://jinja.pocoo.org/docs/dev/api/#basics).

Injecting `--' into the command line is rather funny as it stops
parsing of all following options and treats them as literals, which
dnsmasq then loudly complains about like `ain't nobody got time for
that'.

We now have a branch-adaptation approach so that tools.git can
be a lot less clever as to what goes on internally.  Most meta-
data already comes from here, which is more in line with ports
and plugins.  :)
