FELIX-2287 Improved Handling of queries on the OBR page:
  - accept empty query to select all resources
  - print error message if filter string is invalid
  - fix WebConsoleUtil.urlDecode to return an empty string if
      the value is an empty string (to be inline with the
      URLDecode.decode methods).
  - add resource symbolic name in parens after presentation
      name to differentiate resources with the same presentation
      name but different symbolic names
