Added ProxyDepositRights
Add sticky proxies
Use the devise interface, not warden
Moved properties datastream back to sufia so we can override proxyDepositor
Moved properties about proxies out of sufia
Don't expect a remote user in test
Form stores the on_behalf_of assertion
Create a transfer request when a new GenericFile is created with on_behalf_of is set
Make a sticky proxy when the user accepts a transfer request with sticky: true
