WIP!

/cc @NickHeiner 

## Users
* `npm install angular-translate` should now only load itself without any event.

## Developers
* `npm install` should invoke prepublish because it is locally
* `npm run-script shipit` does all steps except `npm publish` incl. changelog

## CI
* Should be covered: well do only headless tests (because of npm test). Think we should introduce a new config for CI?
For what it's worth, this matches a file or a directory at the root of this project. If you want to explicitly say only a directory (and I think being as explicit as possible is a good idea), then this should be `/node_modules/` with a trailing slash.
