12 Dec 2013 M.Fuerstenau new for version 0.8.16
   - datastore_volumes_info()
     - Some small fixes
     - Changed the output for OK from  "For all selected volumes" to "OK for all seleted volumes."
     -  Same for error plus an error counter for the alarms
   - Main selection - GetOptions. Unce upon a time I had kicked out $timeout unintended. Fixed now. Thanks to
     Andreas Daubner for the hint.
