#1 Add file type field to file scanner / collector messages

[Keith Flanagan]

The file scanner and collector responders deal with locating and acquiring files from a remote filesystem and publishing them to the Microbase resource system. Currently, recipients of a "donwload complete" type message receive the original file URL, and a unique resource id. They currently need to 'guess' whether the file is relevant to them, based on the URL - file extension, originating server, etc.

It would be much better if we had a user-defined set of well-known file type names. The File Scanner responder would store this information along with the other details of a scan target. Any "new file" events fired would be tagged with the appropriate file type.
