Update Rails to 3.2.12.

Security an' all.
Start using Unicorn as a webserver.
Procfile for Heroku Cedar stack.
Refactor film partial.
More tidying and renamed Film#seen? to #watched?

Just following the terminology in the css.
Indent JS.

I don't normally do stuff like this but when it's all over the place it's really hard to read. Sorta like naming layers I guess.

Add the number of films you have in your collection.

Two things:
* It's styled like ass. I don't want to touch the styles, my time isn't best spent there.
* It'd probably be more useful if it showed you both watched and unwatched. I personally don't care about unwatched (I have Thinglist for that) so it's just all films ATM.
