Added object and datastream size calculation and reporting in object profile
Added dynamic reported size for datastream profiles
Added dynamic report of total size to repository /describe endpoint
Almost done. Need to persist the total size of repo (rather than keep it in a field) and write some tests
Now storing repo total size in repo in /objects@size
Added test for size retrieval, moved number-of-objs retrieval to /rest/describe response
Merge branch 'master' into StoreAndRetrieveSizesOfThings

* master:
  More test cleanup
  Cleaned tests, factored boilerplate into AbstractResourceTest
