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
and various DIALOG classes called from top frames. See comments in
{eeschema,pcbnew}/invoke_a_dialog.h.
*) Move some dialog classes into *.cpp files from *.h files.
*) void SCH_EDIT_FRAME::OnErc( wxCommandEvent& event ) was opening the modeless
ERC dialog more than once if icon was clicked more than once.
*) Remove BOM stuff.
