Support for URL values for property "catalogs" in CatalogManager.properties

[Charles Dylan Shearer]

Currently, Resolver allows developers to use paths as values for the  
property "catalogs" in CatalogManager.properties.  I was wondering how  
you all felt about adding support for URLs in this property, so that  
users could specify exactly how catalogs are to be located: for  
example, "classpath:/com/package/catalog.xml" for catalogs on the  
classpath or "file:///directory/catalog.xml" for catalogs on the  
filesystem.

I couldn't tell exactly from the documentation, but it seems that  
Resolver currently interprets these paths as referring to the  
filesystem.

What does everyone think?
