split up help messages for simpler reuse

That is one huge commit with busy work only: Help messages used to be
one big translateable string, which is a pain for translators and hard
to reuse for us. This change there 'explodes' this single string into
new string for each documented string trying hard to split up the
translated messages as well. This actually restores many translations as
previously adding a single command made all of the bug message fuzzy.
The splitup also highlighted that its easy to forget a line, duplicate
one and similar stuff.
