Added
- We now use travis to deploy the package to pypi. That way pypi should always
remain up to date with this repository.
Fixed
- `cocof` would print a misleading 'unknown file format' error, when the
provided json patch contained syntax errors. We replaced this by a composition
of a general warning and an additional specific note.
- Due to an error in the file extension normalization process, `cocof` would
recognize a '.yaml' file as YAML, but not '.yml'.
