An utility class to ease up using property-file resource bundles.
The class support references within the resource bundle set to minimize the occurence of duplicate keys. References are given in the format:
a.key.name=@referenced.key
A lookup to a key in an other resource bundle should be written by
a.key.name=@@resourcebundle_name@referenced.key
