Travis tests fail running on the bare module skeleton

[Rovanion]

Looking at the following test results generated by travis for an empty skeleton generated by this repository: https://travis-ci.org/Rovanion/test-module

It seems as if the dependency named rainbow no longer supports ruby < 1.9.2 and as of such the tests fail. I'm not sure if the right course of action is to remove support for older ruby versions, and with that support for Debian 6 and I assume a lot of Red Hat versions, or to in some way specify that we want an older version of rainbow for the older ruby versions.

Ah, good spot. I'm happy to see that pinned for the moment.

But since rainbow is a dependency rubocop and specifying that we want a lower version ends up with a dependency error. The lowest version of rainbow rubocop allows is 1.99.1 and pinning that has the same effect I'm afraid: https://travis-ci.org/Rovanion/test-module/jobs/91128360
