Abstracted dir list handling from browser.c into dirlist.c

This optimizes a few actions (though not all), and makes the code easier
to understand and expand.

The behaviour of the browser has changed a bit with regards to
multi-page listings. Personally I don't like this change much, so I'd
probably fix that later on.
