Replace mozilla-plugin-adobe-flash with ppapi-plugin-adobe-flash.
The former is compatibility package for firefox.

List network-base is for Communication group and can be not installed.

Add *-base lists on live only.
On the full distro they will be added by the corresponding groups.
Otherwise these packages will be _always_ installed.

Dialers is rather legacy nowaday. But keep it as not-install
for now.

It was commented out anyway.

Drop some apparently not needed packages.

Based on init5-disable-tracker from m-p-d.
