    Banshee.Collection: refactoring around Unknown constant variables
    
    The read-only variables that don't call Catalog.GetString() can be marked
    as a constant instead of static readonly. This may be a micro-optimization
    but it lets us make the static readonly ones reference the constants so
    there is less duplication.
