Add functionality to hide the field in a prepopulated state. Requires a little update to Symphony too
Merge pull request #37 from designermonkey/integration

Add functionality to hide the field in a prepopulated state. Closes #36
Group correctly when a SBL has no value. Closes #35
When using prepareImportValue, if the values passed are not entry ids, assume we've been given the value or handle instead so do a lookup. This should make importing with XMLImporter much much simpler!
