5.5 ede-buffer-object

In fact most of the looking/linking stuff seems to be implemented by the ede-buffer-object method; that itself launches ede-current-project. But the latter in fact only try to retrieve an open project launching ede-directory-get-open-project.

In fact most of the job is done by ede-buffer-object. Unfortunately project looking seems to be done from top to bottom; which is incompatible with the depth mechanism.
