import rhc from Ubuntu vivid

In this commit I imported rhc package from Ubuntu vivid into Trisquel. rhc is the program used for OpenShift.com.

Installing rhc using RubyGems will cause package conflicts, so the best way to solve this issue and improve the stability of the distro is importing rhc from Ubuntu vivid.

I tested the program and it works with no conflicts on Trisquel Belenos.
