Allow non-pjax page updates. 

Extract transition functionality from push.js into a new file, transitions.js.
Expose a global function, similar to PUSH named TRANSITION used to transition
from one page/view to another without dictating how the new markup is sourced.

This allows for Ratchet style page transitions when rendering client side.
