Package name is misleading and should be changed

This repo is not configured properly since it has dependencies that aren't enumerated in `packages.json`.

It also has redundant code to that found in the vanilla angular package.

This has lost me hours of time trying to figure out why `require('angular')` wasn't working when I could plainly see `angularjs` was installed and loaded.

This is essentially namespace stealing / squatting and if you really wanted to keep this package around (which is unnecessary due to redundancy with the core library) then it should be called something like `angular-browserify-shim`
