It's been long overdue, but Planet Grep now does the https dance (i.e., if you try to use an unencrypted connection, it will redirect you to https). Thank you letsencrypt!

I hadn't previously done this because some blogs that we carry might link to http-only images; but really, that shouldn't matter, and we can make Planet Grep itself be a https site even if some of the content is http-only.

Enjoy!
