Enabling Larry Four to generate extended models (suitable for automatic model validation)

This branch can generate models extending base class different than Eloquent, automatiaclly using additional namespaces you specify, and adding a validation rules array stub.

In a handy config file you can set 
- if you want to automatically extend generated models, 
- which models to ommit (use default base class), 
- what should be the extended and default base class and additional namespaces for your models 
- if you want to add the validation stubs

By default, you'll have: 

    class Modelname extend Eloquent {

Now you can instantly have:

    use Namespace\Subnamespace\Something; 
    class Modelname extends Something
    {
        public static $rules = array();
