MockLocalization with Bundle

[nykolaslima]

I am writing tests for a component that depend on VRaptor's Localization

I had to mock each bundle key return by hand. Then I saw MockLocalization but it always use an EmptyBundle.
I did some refactoring in MockLocalization to receive a ResourceBundle when needed.

This way, we can use it like this:
Localization l = new MockLocalization(ResourceBundle.getBundle("messages"));
and we are able to use like it was before, with an EmptyBundle:
Localization = new MockLocalization();
