Asset path without get_current_blog_id #59

Please consider adding a toggle in settings to deactivate the get_current_blog_id from appearing in the URL path. Currently the asset path is composed with a /1/ after the bucket name, and that makes me a bit sad, as I don't have any need for that.

I'm not knowledgeable in WordPress plugins, but I would be glad to learn if somebody else also feels the same way. 🙂
