Display Java method and class names in chrome dev tools.
Chrome dev tools support renaming of functions in compiled
JavaScript by adding a property called displayName to the function.
Throughout dev tools this name will be used instead of the JavaScript
function name, improving the expierence in the debugger, profiler and
timeline.
