Please activate Travis for this repository

With a past pull request, we got Travis support, but we still need to set Travis up in the settings. Please do the following steps:

1. Login into Travis using your Github account.
2. In the Travis profile (for instance, mine would be https://travis-ci.org/profile/k00ni), click on the eye-symbol next to your image. Copy that token.
3. Please add Travis as service here.
   • use the copied token
   • use notify.travis-ci.org for the Domain field.

That's it. With that change, not only ARC2 will be tested but also future pull requests.

Done.

Can you add the Travis link for ARC2 here? I would like to add the Travis badge to the README.md.

Great!
