DM-DM tidying:

- Added NodeCrawlerFactory interface and standard implementation
 - Removed test actions from the context files
 - ensure that the temporary store node is deleted when the transfer ends
 - Added missing error messages from the transfer properties file
 - Inserted abstract NodeFinder and NodeFilter to clean those interfaces up a little
