Added modules to detect and handle the save event

Added the hooking of the application to the event handler in the
"ThisWorkbook" document of the Excel workbook.

NB : the vtkApplicationEventHandler class module is just a draft to see if
the hooking goes well.
Added tests for new vtkExportConfiguration.

Added empty function in vtkImportExport utilities.
Finished writing the tests.
vtkExportConfiguration programmed.

Tests updated.
Updated comments in the tests.
Added handler in VBAToolKit_DEV.xlsm

Played around with it a bit, it seems to work.

Put a Debug.Print that has to be uncommented for demonstration
Corrected tests.

The 'prep' has modified all the Tester files, so they have been exported.
Maybe we should think of a way to avoid this.
Uncommented beforesave handler in TestWorkbook

Added empty function un vtkProjectCreationUtilities
Added function to add the save handler.

Tests don't work as the code for vtkExportConfiguration is not yet in the
add-in, and accessing code from another workbook which is not an
add-in is difficult.

That is to say that calling VBAToolKit_DEV.vtkExportConfiguration raises
an error 424 if we are not in VBAToolKit_DEV.

TODO : add the functionality in vtkCreateProject, when
vtkExportConfiguration will be in the add-in.
Updated tests.

Prep run working.
Added utility functions in vtkPathUtilities

vtkStripFilePathOrNameOfExtension
	Get the raw file name given a file name with extension or a path

vtkStripPathOrNameofVtkExtension
	Same as above, but also removes the specified vtk extension (DEV for
	example)
Moved the BeforeSave handler function
vtkCreateProject : BeforeSave handler in _DEV wb

- vtkMainFunctions
	vtkCreateProject adds BeforeSave handler in the _DEV workbook of
	the created project

- vtkProjectCreationUtilities
	vtkActivateReferences : now adds a reference to the workbook
	running the code (VBAToolKit_DEV or the add-in)

- vtkExportConfigurationTester
	Added test of export on a created project.
Final commit before regeneration of the add-in.
Corrected vtkPathUtilities and Tester.

Others modified files are just because of the general prep run.
Updated vtkAddBeforeSaveHandler.

Tried to fix the export condition in vtkExportConfiguration, did not
manage to.

A lot of modified tester classes because of a general prep run.
Removed tmp module ZZTester
