change href in a tag with htmlFilter doenst work

[Eric Brüggemann]

If you try to apply a filter for the href attribute auf a tags the new value is not written back to the html so.

CKEDITOR.on( 'instanceReady', function( ev )
{
    var editor = ev.editor,
    dataProcessor = editor.dataProcessor,
    htmlFilter = dataProcessor &&    dataProcessor.htmlFilter;
    htmlFilter.addRules({
        elements :{
            a : function ( element ){
                alert(element.attributes['href']);
                element.attributes['href'] = "http://www.ckeditor.com";
                alert(element.attributes['href']);
            }
        }
    });
});

this will first alert the old href than the changed href but the href attribute itself wont change

Editor protects certain attributes to avoid browser touching them, so when in html filter, please manipulate "data-cke-saved-href" instead of "href".
