Change generated model name if option is passed

[davidjr82]

Before, the name of the model was the datatable model itself, instead the model the user was passing with the --model option. Now, if model option is passed, it takes it to generate the model name.

Sorry for late response but I think not passing a --model option would break our generator. I think there is a 2nd argument that sets the default value if none was set?

$this->option('model', str_singular($name))
