Travis integration is broken

[sjakobi]

For example, in #30, there is no indication whether the Travis build succeeded or not.

I have already experienced this in several other repos, and it has already caused me quite a bit of pain.

@HeinrichApfelmus, since you're the admin of this repo, I think only you can fix this. Could you try following the instructions that I posted in quchen/prettyprinter#172 (comment)?

I have clicked many buttons and prayed to the half-filled electron sea. Did it work? Something does seem to be happening:

@HeinrichApfelmus Yes! :)

See #32

Your prayers have been heard. The electronic gods smile upon you.
