Extole integration--cleaned up tests and made a few minor fixes

Made a few slight fixes and cleaned up the spacing on the test suite.
Just to confirm: `this.load` assumes that after the loaded script is finished executing, that the script is totally ready to use. Besides `go.js`, `core.js` doesn't load anything asynchronously, correct? (If it relies on other async script loads, then we should wait on those before calling `self.ready()`.)
