[Zope-CMF] Small CMFCatalogAware refactoring

Hi,

I did a small refactoring on the CMFCatalogAware in changesets [38390]
(1.5) and [38391] (trunk)

The CMFCatalogAware class definition defines now 2 new methods,
_getCatalogTool() and _getWorkflowTool(), that are used internaly while
looking up for the catalog or workflow tool.

This is pretty useful for a given content type to specify a dedicated
catalog or workflow tool. The specific content type just have to
override these methods.

A remaining issue is within reindexObjectSecurity() and the sub-objects
reindexation because, eventually, the sub-objects can be within a
different catalog and in this case if one is overriding the
_getCatalogTool() it will have to override the reindexObjectSecurity()
as well to deal with this. (I put a XXX within this method)

Thoughts ?

	J.
