Ticket #77 (closed irritant: fixed)

Description

The web.xml file provides 2 different styles of links for the file_datastore_loc variable. In production, it's a relative link. Whereas in development it's a fully qualified url. This forces the php script for metadata to be different for dev and prod.

We should be able to just change the dev one to have the relative URL. This will make it consistent with prod. However, the hostname part of the url will still be hardcoded in the php file. It should really be read from somewhere.
