InTheaters: Initial port to the new Spice API.
InTheaters: Add rating.

Convert the critic's score from the 0 to 100 range to the 0 to 5 range.
InTheaters: Change class names and add the actual score.
InTheaters: Add detail template.

It's a modified version of the recipes instant answer.
InTheaters: set critics_score to 0 if it is -1.

It's easier to check in the template because I can just use {{#if}} to check for a 0.
InTheaters: remove unused helper functions.
InTheaters: Add MPAA rating to the detail template.
in_theaters.css: remove unused CSS declarations.
