Add goods

[matthew-parlette]

This adds the concept of an item to the game. You can buy and use items, and the current only items exist in the fast food restaurant. To test:

1. Start Game
2. Move to Fast Food Restaurant
3. Get a Job
4. Work
5. Buy an item
6. Use item

You should see your fatness go up, since hunger is already at 0.

This fixes #57, make sure you include that in the merge comment.

Haha I like the fatness idea. Can you quickly add the cost of an item to the Buy Item menu? Once you add that I think it'll be good.

[matthew-parlette]

I've just added that and tested it, looks like it does what you are looking for

[cparlette]

One last thing, looks like there's some debug output that displays even if debug isn't enabled on the Buy Item menu.

options: {'0': u'Fries ($3)'}
Buying An Item
==============
0. Fries ($3)
(Enter to cancel)

Good catch, forgot to remove that, but I just did

I had to merge this by hand, hopefully I did it right. I used some help from http://git-scm.com/book/en/Git-Branching-Basic-Branching-and-Merging

[matthew-parlette]

I just ran the game for a few turns, everything looks good so I think the merge was correct.
