Thought it would be cool to have Travis CI integration.

Recently, Travis CI announced that [it supports iOS testing](http://about.travis-ci.org/blog/introducing-mac-ios-rubymotion-testing/).

So I check out its sample and attempt to build one for CargoBay.

Hehe. Its quite cool though. Here's a link to [my version](https://travis-ci.org/lxcid/CargoBay/builds/6193555)

The pull request also includes an update to the latest AFNetworking and update project settings.
