Donate link is broken

I’ve updated the donate link in the readme – but know that the link just points back to the plugin page. I’m not seeking donations to support this plugin, as it’s something I’d rather see in core.

If you still want to donate, I encourage you to do so via the PayPal form on http://jumping-duck.com/wordpress/plugins/, directly via Gratipay https://gratipay.com/EricMann/, or by contributing back to the WordPress community itself.
