- Added download members for versions and releases
- Added Delete / Undo for releases
- Fixed bug where model was not set for refset (members screen)
- Moved number of members detail to 'download' popup help

Punchlist of small fixes still to do before moving on to pagination:
- Make versions id based, not publicid
- Remove targetmodel stuff for adding new members to refset
- Cache members screen by using setupController if (members != null)
- Reset cache when adding / removing members, force members refresh
- for create version alert, add link to new version
- add alert screen for new release
- for create relase alert, add link to new release
