View toolbars (with empty names) are no longer added to View/Toolbars menu.

Add a frequency to Catalyst to Live View communication.

The frequency is only added in the Python API and it is hardcoded to 1
in the CoProcessing / Export State wizard. This also fixes a bug that
happens when when CoProcessing / Export State and only Live Connection
is selected.

Remove unnnecessary subclasses of vtkPVXYChartView.

vtkPVXYChartView has subclasses only to set up chart type in constructor.
Instead of doing that, changes all the proxies instead to use vtkPVXYChartView
directly iwth post_creation XML attribute to call appropriate method to set the
chart type on instantiation. Also changed when post_creation method is called.
Now it's called before the property states are loaded thus ensuring that the
vtkPVXYChartView is setup correctly before its methods are called.

Removing unnecessary vtkSMChartRepresentation subclasses.

vtkSMParallelCoordinatesRepresentationProxy and vtkSMBoxChartRepresentationProxy
were really not necessary any more. Removing those.

Also since pqDisplayProxyEditorWidget is meant for deprecated properties panel,
we don't need to make it aware of the new plot types.
