WebPage.onAfterRender compares configurationType String using == operator, not equals method

See http://svn.apache.org/repos/asf/wicket/trunk/wicket/src/main/java/org/apache/wicket/markup/html/WebPage.java onAfterRender method, line reading:

		if (getApplication().getConfigurationType() == Application.DEVELOPMENT)

A String is being compared for identity, not equality, which is incorrect.
