Replaced fwd decls with header includes.

For some reason instead of including some VTK headers, there forward declarations of some VTK classes. This seemed too unidiomatic to leave as is.
Replaced sscanf with stringstream extraction.
Fixed sscanf format string for reading TEMPP sections.
Fixed arthimetic logic error ->

Code was testing for divisibilty with % operator, but wasn't checking that it wasn't moding by zero, which is undefined.
formatting in parseAsProducerVariable()
Handling for AQUEOUS PHASE CONC. OF BIO SPECIES line in HIST files
Removed pqComponentsExport.h include

Interestingly, the PQCOMPONENTS_EXPORT line had already been commented out!
Replaced deprecated vtkTypeRevisionMacro with vtkTypeMacro

vtkTypeRevisionMacro was deprecated with vtk 5.6. I believe ParaView 3.98 uses either 5.6 or 5.8.
Removed obsoleted CollectRevisions calls.
Commented out some code ->

Using SetUpdateExtent and SetWholeExtent from vtkDataSet has been deprecated. Also, it seems they were trying to do this inside of RequestData, which doesn't immediately make sense, since they were also defining RequestUpdateExtent.

Their motivation was that without this, the filter wouldn't act as an input to downstream filters.

This requires greater thought, but in the interest of compiling against PV 3.98, just commenting out for the moment.
Replaced extern decl of vtkOutputWindowDisplayText with including vtkOutputWindow.h
replaced deprecated vtkstd:: with std::
Removed deprecated called to SetPipelineInformation

This is deprecated, but not entirely clear if can just be deleted or if new code needs to be called to replace its functionality.
