Parser improvements

Some things that must be improved in pasdoc parser (PasDoc_Parser.pas), to make it better understand the source code it’s reading:

  • ParseProperty: Parser must be able to understand where are property read and write specifiers names, to avoid including private specifier names in documentation (see Michalis' mail on mailing list "Full declaration of properties is shown" on 2005-05-29)

  • ParseFieldsVariables and ParseRecordCase: Parser must be improved to better understand record fields in records "case clauses" and to understand "records in records", to close pasdoc bug 1199354 completely.
