Playground: Consider simplifying by removing go-angularjs dependency.

I see in neelance/go-angularjs@ae3e8ed that go-angularjs has been deprecated. /cc @neelance The playground currently uses it.

I've personally never liked having to go through Angular here, and wished the playground was written with basic events and DOM manipulation. I don't think Angular is very helpful for this application, and its non-idiomatic-Go API is cumbersome.

Is it okay to try to remove the dependency now and rewrite the playground to use plain DOM elements and events? Thoughts, opinions?

If this sounds like a good direction, I might give it a try and see if it leads to a better codebase or not.

I'm all for it!
