v18.1.1

This release fixes some introduced issues with the installers. It also fixes a few bugs related to some unused columns in the database tables.

Also this version will be the first to go to a true semantic versioning model. The old model was based on a date and just advanced too quickly. So we now get to have a version 18 of ONA. The minor numbers will now just start at 1 and go up as needed from there.
