Subject: refactor(tazjin/homepage): long overdue entry list rework

The entry list is now much more condensed. It's maybe a little *too*
condensed, but already closer to what I'm looking for.

Note: A new "note" post type has snuck in and can now be used for
random musings or comments on previous entries. Notes do not show up
in the Atom feed.
