Subject: show or-groups in not-installed recommends and suggests lists

Further abstracting our new ShowList allows to use it for containers of
strings as well giving us the option to implement an or-groups display
for the recommends and suggests lists which is a nice trick given that
it also helps with migrating the last remaining other cases of old
ShowList.
