Add onClick capability to templates

[Logodaedalus]

Currently hacked into Display.js, but render should be changed from returning just a string to returning
{ text: "some text", onClicks: [{id:"span1", onClick:function deedle() } ] }

and then appending the onClick functions to a placeholder in processTemplate().

Then at the very end, it should by default replace the text with .text property, but should check for onClicks and if the array has stuff, cycle through searching and add them to the elements?

Can't ship with shimmer wishlists unless this is implemented!
