Add the controllers/invokables key when creating controllers

[robertmarsal]

Currently this is not added to the config when creating a controller.

For example :

zf.php create controller Test Application

Will create :

'controllers' => array(
    'invokables' => array(
        'Application\Controller\Test' => 'Application\Controller\TestController',
    ),
),

@weierophinney I'm starting to see a lot of overlap between ZFTool and Apigility... Maybe there's room for making a generic ZF2 application manipulation library, and sharing it across both projects?

[weierophinney]

Ironically, we were hoping to start with ZFTool for Apigility, but the needs of exposing tooling via an API vs the command-line made us scrap that. All told, though, we could likely take the models from zf-apigility-admin and expose those to both ZFTool and the admin interface.
