10 * just to proxy/wrap icons functionality, in case i introduce "themes" later - a theme would be a
11 * different icons.properties file for now
12 * 
13 * if you want to use this, have an icons.properties at the root in the classpath
14 * 
15 * TODO implement registry of cascaded property files etc
