(if I figure out who invented the way numbersep works… grr…)

this is consistent with what I use in MuseScore, so…

as a condition of using their licence marks

increase bottom margin so last line of 3-line licence footer texts
will still be printed shrinking left/right margins a bit in exchange

(unicodedomino.sty version 1.0; the only difference to 1.1, which is
only one commit further, is that 1.1 also works on Debian jessie but
for that to work includes material from LaTeX base as convenience
copy, which we don’t need at Teckids and thus/also don’t want)

(but not actually into a subdirectory, besides, it’s only one file)

This reverts commit 1a4606bdf037c9cb0d85da7ba20816d8275f5a14.

• never(!) load either the “german” or “ngerman” package
  (nor “germanb” or “ngermanb”)
• use appropriate options for the “babel” package, correctly disabling
  shorthands and setting the default language for the whole document

Look at print/leaflet_teckids_common.tex for a deformed German example
(replace a̲l̲l̲ “ngerman” with “german” in the babel line for 1901 German)
and at print/a6.tex for an English example of correct usage.

This reverts commit d11190031ecc0d015da3085391c5a89456c3502b.
