Add a list of sandwiches.

This list of sandwiches is pulled VIA PROGRAMS from the "official" [List of Sandwiches on Wikipedia](http://en.wikipedia.org/wiki/List_of_sandwiches).

My team for Comedy Hack Day used this List of Sandwiches as a basis for our application, [Recommendeli](http://recommendeli.com/) where we extended it for humorous effect. Seems to me having a list of sandwiches might be useful to others as well.
