website cms: banner always has contenteditable="true"

[Ivan Yelizariev]

Steps:
* install trunk OpenERP
* install website module
* edit home page, add banner block, save

Banner block has contenteditable="true", so even anonymous user can click on banner and change content (but cannot save it), button on banner is not working

My suggestion is remove contenteditable attreibute at function "start" or "clean_for_save" at Class website.snippet.options.carousel BECAUSE "start" function (which inherited from
website.snippet.options.slide ) add contenteditable attribute

See main clean_for_save function:

        clean_for_save: function () {
            var self = this;
            $("*[contentEditable], *[attributeEditable]")
                .removeAttr('contentEditable')
                .removeAttr('attributeEditable');

            var options = website.snippet.options;
            var template = website.snippet.templateOptions;
            for (var k in options) {
                if (template[k] && options[k].prototype.clean_for_save !== dummy) {
                    var $snippet = this.dom_filter(template[k].selector);
                    $snippet.each(function () {
                        new options[k](self, null, $(this), k).clean_for_save();
                    });
                }
            }
        },
