unified packaging: cleanup and simplification
add manpages

- New wineVERSION-doc package.
  Multi-Arch foreign to avoid conflicts.
- Install all manpages from upstream mandir (generic).
  This includes manpages for programs that are not installed to path, but
  in /usr/lib/*/wineVERSION/. But IMO even this way the manpages are of
  some use.
  They might be patched to show how to call the programs.
  Or the programs could be installed to path, which is a bit complicated
  (probably not desirable) in respect to multiarch.
- Add update-alternatives (hardcoded for the moment) for master wine.1.gz.
  This still needs a little manual adaption for wine stable (still works
  though).
  Adding the manpages as slaves to wine would require the wineVERSION
  package to Pre-Depend on wineVERSION-doc.
  Breaks wine << 1.6.2-9 (assuming this is applied to the next release
  1.6.2-9).

TODO:
- lintian overrides (binary and manpage in different packages).
- Fix more hyphen-used-as-minus-sign occurences.
- Probably move all READMEs to this package.
