2.2.0

- Feature: Moved to Eclipse 3.3 - note that a full re-install is needed for this release
- Feature: Inferences Explanation view. This converts Pellet explanations and explanation axioms
		   to explanations in TBC. You can use the "Explain Inference" menu item in the drop
		   down menu behind the form to activate and see the inference explanations and you 
		   can navigate to shown resources.
- Feature: Added support for the native AllegroGraph SPARQL interface (in the drop down menu
           of the SPARQL view).  Note that this only works on a single AllegroGraph, i.e. no
           imports are supported.  Furthermore it only considers the committed triples, i.e.
           uncommitted changes are not delivered. 
- Feature: Export to AllegroGraph now also supports incrementally adding to an existing graph

- Bugfix: UML Importer is now more tolerant against different spellings of datatypes
- Bugfix: If a file has more than 10 imports, only the first 10 are automatically opened as editors
- Bugfix: Typed top-level blank nodes are no longer converted into URIs at load time
