Moved Team and Caliper Attributes lists into tabs

added Bootstrap tab markup to tabbed-menu.hbs

in superheroes.hbs now invoke tabbed-menu.hbs via a view rather than as a partial

new tabbed-menu view which activates tabs after the template is inserted

(I know Graham is going to update the layout - fine by me if we don't use this code, it's just been bugging me that I didn't get it working, so now I have)
