Adding Travis-CI build validation to RBL 1.0 branch, etc.

I wanted to share some of my recent work on this project:
[Running AS3 Projects With Travis-CI](https://github.com/Larusso/travis-CI-actionscript-demo), with the RBL community.  This change really doesn't do much more then run the existing Maven build process on Travis-CI so that we can have this cute icon in the README.

[![Build Status](https://travis-ci.org/haysclark/robotlegs-framework.svg?branch=version1)](https://travis-ci.org/haysclark/robotlegs-framework)

This pull request is just updating the 'version1' branch.  If people like the minor change I can add this work too the other branches, or any other author could make the change.  Someone with Admin right to the 'robotlegs' GitHub user account will need to [create a Travis-CI account](https://travis-ci.org/) and then 'enable' the __robotlegs-framework__ repo.

There is also a nice Travis-CI zsh plug-in.  Please let me know if you have any feedback.
