reduce byobu recommends

Binary package hint: byobu

Some people have raised a concern about Byobu bringing in too many recommended packages.

The current list is:

Depends: ${misc:Depends}, debconf (>= 0.5) | debconf-2.0, screen, gettext-base, python, python-newt (>= 0.52.2-11)
Recommends: update-notifier-common, lsb-release
Suggests: apport, vim, w3m, po-debconf

Of these, both of the recommends can be dropped to suggests (update-notifier-common, lsb-release).
 * update-notifier-common: needed to check for package updates
 * lsb-release: helps to determine the release name (if not present, it uses /etc/release)

Of the dependencies,
 * debconf: needed for the debconf launch-by-default question
 * screen: obviously, provides the raw functionality
 * gettext-base: needed for translations
 * python, python-newt: needed for the byobu-config curses configuration menu
