Bump glent to 0.2.4
This includes all of the changes made for Method 2, the dictionary
suggester, over the last few months.
- Update glent jar from 0.2.3 to 0.2.4
- Add symlink for glent-latest, following how rdf-tools works. This makes future updates simpler as they can update the symlink without repointing the dag or changing fixtures.
