Partial Implementation of new password UX for Document Sharing.  Successfully setup delegation pattern for communicating between DocShare and passwordPicker view controllers.  Once implemented will do same for Link Expiration Dated to use delegation instead of storing the Link Expire Date in the appDelegate, as currently coded.
Updated DocSharing Password Picker so it only launches if passwordPicker is selected.  If deselected, does not launch pickerView.
Finished implementation of Password Feature when creating a link
Tweaks to Password Link Generation
Updates to PasswordPicker and LinkExpiration, including device Rotation fixes for both and new UI/UX
