Replace unused arguments with _

This patch replaces a large number (but not all) unused arguments with
the standard ``_`` placeholder. This has the advantage of signaling that
these values are unused.

There are a number of places that I've chosen not to apply this, largely
in methods that have publicly define signatures that they inherit
(usually from urwid).
