Add link for "Uri" objects

Message Registry File resources contain a "Uri" pointing to the
location of the Message Registry.  This change makes the "Uri"
object a link that can be clicked to jump to the Message Registry.

Tested:
Verified that the "Uri" field is a link and takes you to the
Message Registry.
