cweb #10129937 ui: menu when click on icon [open]

Refactor the ui that is displayed when the extension icon is clicked.

  1. sidebar on/off (clicking makes the sidebar dis/appear)
  2. link to the option page (opens in another tab)
  3. "checked mark" + name of the view auto-selected
  4. list of views that did not return the -1 priority
  5. item pure rdf (displays the source without rendering it)

Clicking on one of the views changes it to the active view: it has the "checked mark" and it is used to render the tab content.
