Update an existing Heroku deployment

Once you've run bin/setup_heroku, you should have 'cantino/huginn' as a remote in git. (Check with git remote -v.) Now, you can update your Heroku installation with the following commands:

git fetch origin
git merge origin/master
git push -f heroku master # note: this will wipe out any code changes that only exist on Heroku!
