[Aleph rest-dlf connector] Completed refactoring of LookupRequest's SAX handler (AlephLookupRequestHandler)
Implemented:
1) parsing ItemUseRestrictionType
2) parsing & successfully forwarding ISBN as BibItemId & Barcode as AccessionNo in ComponentId
3) made all RequestElementTypes desirable (not forwarding all if not specified as before)
4) deducing PickupDate based on settings in toolkit.properties (row called MaxItemPreparationTimeDelay) - where the set value in days is added to RequestPlaced (if it is not disabled using value of 0 days)
5) parsing Location initially leveled as level 1 (z30-sub-library)
6) parsing z30-description into HoldingsInformations as UnstructuredHoldingsData instead of unappropriate ItemDescriptionLevel
7) forwarding unformatted status node into SponsoringBody
8) fix of inappropriate RequestType (initial was Estimate -> now Hold)
9) minor changes not affecting toolkit behavior
