startWithParent should be a Module class prototype property

When module uses the ModuleClass directly, `MyApp.module("Foo", ModuleClass)`, the start with parent option should be plucked from the class prototype. This does not currently happen.

```js
var ModuleClass = Marionette.Module.extend({
   startWithParent: false,
    initialize: function(options, app, moduleName) {
        console.log('init module');
    },
    onStart: function(options) {
        console.log('start module');
    },
});

MyApp.module("Foo", ModuleClass);
MyApp.start();
```
