App.namespace in module template should come before the inject:folders tags

[Joshua Skrzypek]

https://github.com/mcfly-io/generator-mcfly/blob/master/templates/module/index.js#L22
this:

    var app = angular.module(fullname, ['ui.router', <%- ngModules %>]);
    // inject:folders start
    // inject:folders end
    app.namespace = app.namespace || {};

should be this:

    var app = angular.module(fullname, ['ui.router', <%- ngModules %>]);
    app.namespace = app.namespace || {};
    // inject:folders start
    // inject:folders end
