Configuration for continuous integration service

I needed to change a lot of things: **i)** add a travis config file, **ii)** updated library qunit to the last version, **iii)** fix some url path and **iv)** so forth...


[Travis](http://about.travis-ci.org/docs/) is a hosted continuous integration service for the open source community. Take a look [here](http://about.travis-ci.org/docs/user/getting-started/) to know how easy is the configuration for continous integration service.

I hope you will like it.
