Travis CI Support for Formotion

Now that travis-ci.org allows to add RubyMotion and iOS projects (YAY for that) we should add it too.

I've tested it and [it works as expected](https://travis-ci.org/mordaroso/formotion)

Steps to add formotion to travis:

1. Login to travis-ci.org
2. Goto [profile page](https://travis-ci.org/profile) and activate formotion
3. Accept pull request
4. Watch the project compile and run the specs
5. [Add a status image to the README](http://about.travis-ci.org/docs/user/status-images/#Adding-Status-Images-to-README-Files)
5. Profit!
