Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
Also updates AUTHORS.txt from current repo with contributor names
Also fixes a bug where the pretty printer didn't insert
linebreaks for a forest (it assumed a single tree root).
Also further regularises bool and quote formatting.
Like the DSNLEXER header, this has visibility in over 700
files, whereas well under half actually use any of it
(quite a bit, but not all, of it actually via DSNLEXER)
Many places already forward-declare the OUTPUTFORMATTER type,
by doing that for the others, it still possible to use the
non-IO methods without having to see richio.h.
The dialog allows a color selection for each dielectric layer.
However for a "dielectric" defined by more than one layer, the color was handled
only for the first layer, and not for the other sub-layers.

Use KiCad default stackup for older CADSTAR boards that do not
define any dielectric layers between the electrical layers.
Also fix default stackup calculation to ensure finished board thickness
is 1.6mm
They don't define a KiCad string class, so the header file name was
somewhat misleading. But the fact that they didn't match definitely
made coding more difficult.
