Added eject, iw and alsa packages to the list.

Eject is just useful, iw seems to be the succesor for cli management of
wireless and alsa for audio (need to figure out how to 'disable' pulse).
Added some 'forgotten' packages from task-desktop.

The menu and xdg-utils package ensure proper integration of programs
into the menu.
The proprietary video drivers were already included, but they don't
support older hardware, therefor including
xserver-xorg-{video|input}-all packages (which are depends of the
task-desktop package).
