Updates Foundation Component, compiles successfully

This updates Foundation, everything seems to compile successfully now. I added an empty `.gitignore` file, too. If you want, you can ignore `www/` so you don’t have compiled files in your output. You can also ignore `components/` if you want; by adding a `component.json` file, then someone can just run `component install` in the root directory and Foundation will be added. Totally optional, though!
