Log Message:
-----------
loading of persisted ResourceReference instances now works (or at least my test
passes) with proper handling of $ etc. This is done by gerneralizing the way
URLs are handled so the same code now works with URLs and URIs. So if something
stops working with a URL this is probably where I should look for the bug
