i#108348: support DateTimeWithTimezone in user defined Document Properties

- fix interface of sax::Converter to allow passing time zones
(rename the parsing methods while at it to reduce pointless overloading)
- SfxDocumentMetaData supports DateWithTimezone and DateTimeWithTimezone
in user-defined properties
- add some ugly hacks to SfxCustomPropertiesPage to preserve existing
time zones (which are not displayed in UI currently)
