*Title: Enhancement to module redirection methods

*Documentation:
The redirection methods in eZModule has been given to extra
parameters which can be used to specify user-parameters and
an anchor. If supplied they will be appended to the resulting
url.

e.g.

// in content module
$module->redirectToView( 'view', array( 'full', 200 ),
                         null, array( 'MyParam' => 42 ), 'list-of-items' );
// generates URL
content/view/full/200//(MyParam)/42#list-of-items

The methods that support this are:
redirect():
redirectToView():
redirectModule():
redirectionURI():
redirectionURIForModule():
