Rating system and comments (Patreon)

You can now rate and comment on pictures in the gallery!

visit it here: http://patreonwhiteraven.com/public/gallery 

I've only implemented the backend of it, (the server side).

I'm going to style it later, hence the ugly look!

I've got a question though, to not be able to rate infinitely many times on a picture. I need to collect user information, such as IP-addresses. (Many sites are collecting huge amounts of user informations, I'm not going to collect more than your IP-address AND I'm asking politely :D)

Is this ok?
