Data Importer - latest updates

You'll see a number of small updates land today that make Data Importer easier to use:

Cleaner rendering of the Graph Model and drag-out relationship creation
Constraints created by Data Importer to perform loads are now prefixed
imp_uniq_
so you can easily identify them
When you only have one file in your files panel, we'll assume that's the one you want to map and automatically select it in the node mapping panel to save you time
When running in Workspace, Data Importer now gives you the option to
Start Exploring
in the Explore tab rather than Query after an import completes. Standalone Data Importer continues to provide a link to Query in Browser
Cypher statements shown in the Load Summary now have syntax highlighting
