Do not swallow existing templates in the plugin folder

This release changes the behaviour of the template loading. Previously, existing templates in your theme-folder were thrown out in favour of the templates specified in resources/views/{post type}/{name}.blade.php, even if there were no such templates.

This release changes this to extend the set of available templates. If for example you define a template in the theme, and another in resources/views/*, these will both be available for use in the Wordpress-administration.
