Release 3.0.5
- Verify that vocabulary terms defined in snake_case are not automatically converted to camelCase.
- Remove the ability to set the external encoding when writing N-Triples, as N-Triples requires UTF-8.
- "Fix" syntax in vocabulary.rb that Ruby versions < 2.2.5 don't parse properly. Set Travis to test on 2.2.2, not just 2.2, which defaulted to 2.2.7 at the time of this fix.
