Make Grouper work with Subject API 1.0

We need to accommodate the Subject 1.0 API. Need to discuss exactly what this means i.e.
1) Can we support 0.3 + 1.0 at the same time - just ignore type for 1.0? Implications for LDAPPC?
2) Do we need to add a meta data layer + SubjectFinder type functionality in the Subject API first?

There will be a fair amount of tidying up in the UI once we remove type (assuming we do)
