Title: Updated Models.markdown to require 'data_mapper' instead of 'datamapper'

In going through the Sinatra book, I received an error when trying to require 'datamapper'. In looking at the latest documentation on the DataMapper site, it looks like it should be 'data_mapper' instead of 'datamapper'.
