Add a robospice-retrofit2 module

Add a robospice-retrofit2 module to be able to use Retrofit-2.0.0 and up with RoboSpice

@mykolaj I looked into why these builds were failing and it looks like it's because you didn't push the changes to your submodule for retrofit2. If you push the submodule changes first, followed by the main repo changes, it should work.

@aliceharrison OK, I'm going to need to refresh my memory a little about this issue, and will do everything from my side after that.

@mykolaj Did you push the code with support of retrofit two?

@SanyasiraoM Please follow a link to check out my repo with a demo on how Retrofit2 can be used with Robospice: https://github.com/mykolaj/Robospice-Retrofit2-sample
Although I've created a pull request, I doubt that it would be merged and/or released any time soon.

// ---- BEGIN
In case someone need to use Retrofit2 with RoboSpice take a look at a sample repository.

What you can do is to clone that sample, take '.jar' files from a 'libs' folder from here, and import // them into your own project.
git clone https://github.com/mykolaj/Robospice-Retrofit2-sample.git

That's all for now.
