implement a more generic ShowList method
apt-get is displaying various lists of package names, which until now it was building as a string before passing it to ShowList, which inserted linebreaks at fitting points and showed a title if needed, but it never really understood what it was working with. With the help of C++11 the new generic knows not only what it works with, but generates the list on the fly rather than asking for it and potentially discarding parts of the input (= the non-default verbose display). It also doubles as a test for how usable the CacheSets are with C++11. (Not all callers are adapted yet.) Git-Dch: Ignore
