TVB-1483
Change the way default data is imported in TVB (no longer using Adapters but a ZIP project import).

git-svn-id: https://repo.thevirtualbrain.org/svn/tvb/trunk/tvb_data@6601 1c0e02f0-7929-43c0-8fb3-3293bf43b0d1
TVB-1483
Remove deprecated code in our CFF importer.
Our old demo-cffs are no longer importable, but the new importer code should work with the CFFs we got from users.
