[BlueBream] ftesting.zcml

[Christophe Combelles]

I think there is something wrong with the ftesting.zcml in the bluebream 
template. It should try to replicate the site.zcml, but does not contain the 
same thing. So the functional test by default don't use the same registrations 
as the real application.

During the week-end I've tried reorganizing the zcml files, but I could not 
obtain something acceptable.

I think the ftesting.zcml should just <include> the other zcml files (the same 
as site.zcml), and just override what is needed to be changed for the tests (ex: 
the manager account).
But to include these zcml files, we should move the content of site.zcml into 
the src folder, and just keep some <include file="...">.

What do you think?
