chore($browser): remove the addJs method
this was never meant to be a public api used by apps. I refactored the code to hide the functionality. BREAKING CHANGE: $browser.addJs method was removed apps that depended on this functionality should either use many of the existing script loaders or create a simple helper method specific to the app.
