Remove collections from descMetadata after assigning Collection objects
Remove comment marker from MediaObject before_save callback
Smarter, just-in-time collection creation

Adding stub for group migration
First cut at a migration of the system groups
Add 'ActiveRecord' migrations for avalon.yml and MediaObjects.
Require hydra-migrate >= 0.2.0
Fix avalon.yml path in config migration
Don't try to migrate content if there are no MediaObjects – solr gets confused
Remove the unnecessary <str name="defType">lucene</str> that causes Tomcat+Solr to whine
Work around Admin::Group#name_changed? bug
Update VERSION constant
Don't change discover/read rights if the object already has explicit ones defined
Replace the 'collection_manager' group with 'manager' in object rights
Update active-fedora and hydra-migrate
Create an administrator group if it does not already exist and use the first person in group_manager as the default value
Remember to actually _save_ the administrator group after you add a default user
