Expunge all FontList usage, replace with CompoundString tags.

20 or so Widget constructor calls included a :FONT-LIST initarg, which
had the effect of superseding Xt-based configuration mechanisms (e.g.,
X resource files). This turns out to have been unnecessary, since
Motif's XmString type includes tags whose purpose is to direct text
styling.

This commit simply rips out all Font Lists while ensuring that every
place a FontList was used instead uses a CompoundString with an
appropriate tag, one of "header" or "italic".

Given those tags, it becomes possible to achieve all the previous
styling effects just using Xt/Motif machinery, e.g. by putting
something like one or the other of the below examples into the user's
~/.Xdefaults or an app-defaults file named "Lisp".

(A subseqent commit will arrange for these defaults to get set as
fallback resources when the GUI starts up, so that no external
resources file will be needed, and so that users who prefer to
configure things from within Lisp can do so.)

Sample .Xdefaults content; use one or the other, not both.

!! Core X11 Fonts

!! First, setup the defaults for the RenderTable.
!!

!! Define a rendition called "header", and specify its font.
