Bring new sbt services using the event stream api

removes the old sbt.js apis. Now, you have to use the new Websocket and EventStram API

```js
define(['commons/websocket', 'commons/types'], function(websocket, types){

  var stdout = ko.observableArray([]);
  websocket
    .subscribe({ type: 'sbt', subType: 'LogEvent', event: { entry: { message: String, type: "stdout" } } })
    .each(function(message){
      stdout.push(message);
    });

})
```


in sbt terminology these are "projects" and the whole app we have open is the "build" (we can call the stuff whatever, but it may be less confusing to stick to sbt)
