Fixed empty vector access problem found by -D_GLIBCXX_DEBUG.

Added option -dist

Extended tGSAservice with tests for the PVSSInfo class and made it more
robust by delteing leftovers from the previous test (if any) before starting
the new tests.

- Added get_result() stored procedure.

- Added trigger/notification for insert of initialize, finalize, nextchunk results.
- Updated add_result() stored procedure, now returns bool.
- Removed command_queue_empty() as it was no longer used.

* Re-added "Operation" field.
* Added functions to add Initialize, Finalize and NextChunk commands.

Don't close filehandles (for a while), default initialize APAdmin name and more
extensive used of this name.

New Olap user panel added, removed old one.

changed Split command

Added #ifdef for Apple problem

Added support for multiple fields

Not substracting the parameter subset anymore.

Update to use the renewed datapoints.

Fixed coding bug which only surfaced when compiling with -D_GLIBCXX_DEBUG.

Some reformatting and merge of salPing and salEcho into tGSAservice. The tests
done in tGSAservice are copied from salEcho and are not very clever yet and
definitely not covering the whole GSA_Service class!

A whole bunch of code changes. Most notably:
* All BBSStrategy and all BBSStep classes now inherit from the Command base
  class.
* CommandVisitor is used in quite a number of places to "restore lost type
  information"; i.e. to recover the exact type of a Command.
* CommandQueue now stores and retrieves Commands instead of BBSSteps and
  BBSStrategy.

Further small changes to names according to nameConvention
