This is a proposal for how to hook into the creation of the ViewMetadata to add a UIViewParameter if necessary. Another way to override the ViewDeclarationLanguage is to provide a custom factory. However, overriding the ViewHandler gives us the opportunity to hook in other functionality in the future.

Feel free to rename or repackage the classes as needed.

> <s:viewAction> tags in the <f:metadata> tag are not processed if there are no viewParams present.  Override the ViewHandler and return a wrapped version of the ViewDeclarationLanguage.  When createMetadataView is called, we delegate to parent, then, if there are components in the view metadata, but no UIViewParameter, we add a dummy instance.
