[web] Wrong behaviors in the CWPropertiesForm from the cube web

With the cube web, the CWPropertiesForm used with views like /myprefs or /siteconfig have wrong behavior:

• In the components and ctxcomponents widget in the /myprefs view only show items called ctxcomponent instead of the correct label.
• With the same widget, its no longer possible to expand a single item by clicking on the label
• The label and the “Show all” links use javascript:$.noop(); as href. Its not really useful and very ugly when the web navigator show this text instead of the URL as tooltip.
