Fixed a typo in FabricCanvasViewport
Added user first and last names to graphs returned by web service
Added a print_triples debugging utility functions which prints a turtle serialization of an iterable of triples
Fixed a bug with building project metadata graphs when using 4store

The use of transaction.commit_on_success() was causing 4store to hit
its soft limit for unknown reasons
Removed other occurrences of transaction.commit_on_success when used only for RDF data

(As this has been observed to cause problems with 4store, and the
Django transaction management doesn’t really work with 4store anyway)
Added full user name and email address to user account tooltip in base.html template
