Adding dojo_lists.html which has tree, tree label class changing, icon changing (not working?).

Added the custom templated widgets:
    AuthorWidget - the one from tutorial
    ListItem - just the <li/> item, to add functionalities
    CollectionButton - Just a standard <button />, code apply custom baseClass for stylings. This is for Collection_R.
dojo_Stylings.html uses AuthorWidget and CollectionButton - two templated custom widget with inner custom HTML.
