docs: Adds a new {@link JQMListItem} that contains the given @param text as the content. Note that if you want to
  navigate to an internal url (ie, another JQM Page) then you must prefix the url with a hash. IE, the hash is
  not added automatically. This allows you to navigate to external urls as well.

  If you add an item after the page has been created then you must call .refresh() to update the layout.

  The list item is made linkable to the @param url
