Fix undefined object error on IE
Merge branch 'fix-ie' of git://github.com/n11/bullet
Re-added registered key to bullet.app.src

In order to build an app using bullet (in elixir) with relx i was
unable to include bullet since i was getting the following message:
“bullet: Missing parameter in .app file: registered”
The (re)inclusion allowed to build the app with relx
Fixed whitespace.
