Improving the installer

Hello,

I had an idea about this installer: enable a customization of the basic project.
It would allow to modify the configuration of the project by choosing the which version of laravel to use, the Test Framework (PHPUnit, PHPSpec,...), the database engine to use by default, the main namespace of the application, and some other options.

I want to have your input on this implementation before continuing this work.

Cheers!
