Continuous deployment

@exalted It would be great if you could take a look at this as well. 
```diff
-  - cp config/database.yml.travis config/database.yml
-  - psql -c 'create database travis_ci_test;' -U postgres
+- cp config/database.yml.travis config/database.yml
+- psql -c 'create database travis_ci_test;' -U postgres
```

Why this change?
