Change the JSF preRenderView to fit the new viewAction

When a JSF page is generated, it uses the old JSF 2.0 preRenderView :

<f:event type="preRenderView" listener='#{authorBean.retrieve}'/>

Instead, it should be using the new Java EE 7 viewAction :

<f:viewAction action="#{authorBean.retrieve}"/>

I've replaced all occurrences in every pages and it works fine.
