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.
* Correct all user strings and comments for the correct capitalization of
application names according to JP. They are KiCad, Pcbnew, CvPcb,
Eeschema, and GerbView.
* Add a note the the user interface policy about the correct capitalization.
* macros.h now has TO_UTF8() and FROM_UTF8() which are working converters
to and from UTF-8 encoding for any wxWidgets build mode. We can switch to
them at any time. I am using them now for specctra conversions and
elsewhere where I wanted gauranteed UTF8 encoding.
* added OUTPUTFORMATTER::Quoted( const wxString& ) to simplify converting
to UTF8 encoded s-expression atoms. The recommended technique is now simply:
out->Quoted( wxString ).c_str()
