  • reintegrated branch 'db'
    • GBDATA now is a base class of GBENTRY (new) and GBCONTAINER
      • moved code into classes GBENTRY, GBCONTAINER and GB_MAIN_TYPE
      • several functions now exist 2 (or 3) times (for GBENTRY and GBCONTAINER, and some for GBDATA as well)
      • several functions changed their interface (caller has to explicitely pass GBENTRY or GBCONTAINER)
    • dropped support for ARB DB-version 0
  • adds:
