Compress patch from the neomutt repository.

With the following changes:
- po/de.po changes trimmed to just the compress additions.

- Move the sample muttrc to contrib, and add it to the Makefile.am so it is
  distributed.  Remove the sample vimrc.

- Remove extra fluff from manual.

Thanks to Roland Rosenfeld for the original patch, and to the NeoMutt
team for their work cleaning up the patch.
