Current behavior

Running an Angular2 application with ng2-translate fails because it looks for traceur.js but fails to find it. In RC6, you should import the bundles as described by @robwormald in his gist.

As I believe, you where already in contact with @robwormald for this?

Expected/desired behavior

To just work out of the box 😃.

Reproduction of the problem

Upgrade to RC6, load in the bundles instead and it will fail with the traceur error.

What is the motivation / use case for changing the behavior?

Because ng2-translate seems to be unusable in RC6/

Please tell us about your environment:

• ng2-translate version: 2.4.2
• Angular version: 2.0.0-rc.6
• Browser: all
• Language: TypeScript (1.8)
