Advanced options

This PR adds "advanced options" to the Vagrant settings box. It also changes the default Vagrantfile to use the Vagrant Cloud, maintaining an option in the "advanced" section so you can unselect the use of Vagrant Cloud, which will then include the full box url int he Vagrantfile.

You can choose if you want to enable Windows compatibility (ON by default) and also the type of syncronized folder (NFS by default).

Removed the old lucid box.

About the current tests: I don't think the BundleControllerTest is going in a good direction. I will create a new branch and PR for implementation of functional tests using the Symfony WebTestCase component.
