Client mode attachment type

Where a Client Mode Attachment Type is being used, the user can search and select a file from any location to which they have access.

Once selected and the paperclip record is saved, a copy of the file selected is saved onto the network in the default location specified for the Attachment Type.

The Upload New File indicator has been hidden on the UX form since it is no longer applicable. For Client Mode, a copy of the attachment file is always uploaded.
