Standardized the request params initialization

The parameters for module, controller and action were build up in every action and were implemented with some inconsistencies. This PR tidies up and implements standardized request parameters for all action methods in the CreateController. These parameters now follow the ZF2 coding standards:

For users who do not want to follow these coding standards an optional parameter was introduced. If the users adds "--ignore-conventions" or "-i" at the end of the "create module", "create controller", and "create action" command the coding stanards are ignored to give more flexibility.

In addition the code is generated with Zend\Code\Generator and adds DocBlocks skeletons. Also the CreateController was tidied up a little to follow ZF2 coding standards.
