I would not add the locator alias in front of the resource name, that 
would look like an URL, but I like the idea. We could just add a locator 
attribute :

<properties locator="classpath" fileName=""/>

I don't think so, the location mechanism is specific to the loading of 
the file, saving is a different beast, once the file has been loaded 
it's expected to be saved at the same place. That why I didn't want to 
remove the internal URL in AbstractFileConfiguration.
