Delete ref set now works through the data manager and prompts user for confirmation first
Import flat file members also now works through the data manager and has its own error handling - although API response does need to be changed and UI updated accordingly.
Update ref set now identified members that have been changed (active status or moduleId) and only includes those in the update refset call.
Not yet implemented adding (importing!) members to an existing ref set, but hooks in place for dealign with them when I do.
Not implemented deleting members yet since we need a build delete function
Noticed that moduleId is missing from members.
Bulk add members still only adding IDs, not objects... (not suitable for RF2 import)
No validation in place yet for new / update ref set
Merge branch 'develop'
