Resolved crashes when input file contained unspecified tags (including tags, starting from underscore).
Access to _tagStore and _rootTagsByCode now made through single serial queue.
_tagInfo was done over NSDictionary (thread save).
For thread safe reasons 'isBuildingFromGedcom' made over atomic property instead of ivar.
Thread safety improvement.
GCDate simple date constructor was added.
UTF-8 for GEDCOM export now supported.
Some files were localized on languages: german, russian, spanish, italian, portuguese and french
Thread safety improvement.
