feat(angular2-app): allow to easily add vendor files

[cironunes]

to be able to easily add vendor files in generated projects:

var Angular2App = require('angular-cli/lib/broccoli/angular2-app');

module.exports = function(defaults) {
  var app = new Angular2App(defaults, {
    vendorFiles: ['material-design-lite/material.css']
  });
  return app.toTree();
}

@cironunes This other PR seems to be more complete, what do you think? #135

[cironunes]

Closed in favor of #135

[cironunes]

@filipesilva actually this is another thing. This helps to add vendor files, any of them, not just ng libraries. Can you review this one?

Closes #140

[filipesilva]

Got it. Lgtm but seems to have merge conflicts, can you look at that?

[cironunes]

sure
