Move status dom into js app for easy reuse

Provide helper zuul_build_dom and zuul_start functions to ease resuse
of the application. All somebody needs to do is call these two
functions to get a full status page built for them.

This still keeps the jquery.zuul plugin separate for individual
consumption.
