Make Route 360 compatible with Zepto
Make Route 360 compatible with Zepto

In order to not have to pull in all of jQuery for my existing project which so far hasn't needed jQuery, I'm trying to use Zepto as a jQuery alternative.

The only difference between jQuery and Zepto that has caused a problem so far has been that .offset() returns `undefined` in jQuery and `null` in Zepto.
