Wayne Stambaugh e1900161a7 Eeschema: implement new symbol library file s-expression formatter. 
CHANGES: Symbol library file format has been converted to s-expressions.

Add support code for picking apart symbols at some future junction that
will allow full inheritance conversion of existing symbol libraries.  For
now, symbols arranged by unit and body style numbers are nested for round
robin testing of symbol libraries once the parser is complete.
