Custom taxonomies and generic source code enhancements

In this new version, you can now declare custom taxonomies for WordPress (custom) post types.

For example, you can declare a new people taxonomy for WordPress posts like this:

taxonomies:
    people:
        object: post
        label: People
        public: true
        show_in_menu: true
        show_in_nav_menu: true

You can see the list of all available arguments in the WordPress Documentation.
