Animal directories are not protected

[bamyasi]

When new animal is created via plugin's Add new Animal tab, no .htaccess files are copied/created to protect its 'data' and 'conf' directories from improper access. Hence, typing a fully qualified URL, e.g. http://localhost/farm/animal/data/, will produce index of all files in the animal's data directory. Same for the conf directory. This could potentially compromise site security.

Animals should be created outside the web servers document root. Adding a .htaccess for good measure might be a good idea anyway. PR welcome
