Heroku Deploy

Our app is heroku ready!
Seeeee http://pacoballs.herokuapp.com/

the issue was that we use sqlite3 as database and heroku uses postgres and doesn't support sqlite3. 

You have to run ```bundle install --without production```. It will only install the sqlite3 gems, not the postgres ones.
Because we don't have a postgres-db installed on our local machines it would fail.
