Fixed bugs, added tokens.

- In vtkXMLUtilities
	- fixed bug when exporting a project's configuration while exporting its XML sheet.
	- used the same trick than in vtkRecreateConfiguration

- In vtkMainFunctions
	- worked around bug when activating certain references in a recreated configuration

- In vtkNormalize
	- added normalization tokens. Though I had to normalize the files by hand : there's probably a problem.

Saving is now quite slow.
