Resurect the standalone url in lists and metrics views

• Le list views as well as the metrics have a standalone URL.
• With the commit dd6e98f8, it should work again for the list. This is true in the dev environment but not on the server marprod.
• For the metrics, the URL is not working since the JavaScript librairy Ext JS is missing.
• A possible way out is to add a new parameter in the selector, e.g standalonewith the default valuefalse.
• The standalone parameter is set to true when using the standalone URL.
• The controller list/index is the almost the same. the only change is the selection of the view which depends on the standalone value: eitherlists/index.htmlorlists/standalone.html`.
• The html page standalone contains the header and the body. In the header contains the Ext JS and the MathJax libraries. The body include the index.html view.
• The default value can be set in existing list and metric by adding baseParams={'standalone': False} when building the lists/metrics node in the main viewport.

TODO:

• modify the controller lists/index.html
• add the view views/lists/standalone.html
• modify the node lists in viewport
• propagate changes to metrics and even to graphs
