Support template engines that return DOM elements

[reno1979]

When my templating enginge (CANJS) renders a template it returns a DocumentFragment, can Typeahead handle this?

(also more efficient than normal HTML appends )

ok, this solution works

can.compile = function(templ) {
      return function (ctx) {
                var divElm  = document.createElement('div');
                divElm.appendChild(can.view(templ, ctx));
                return divElm.innerHTML;
            }

    }

This isn't currently supported but I think it may be pretty easy to add make this possible.
