v2.1.2

This release contains several bug and ui fixes including:
- SMTP not working under SSL, new settings.yml entries had been added for advanced customisation for this use case
- Extra font support for text editor
- Change password/username UI added for users
- Change password for admins added
- Possible fix for swagger access issues
- Fix for admin ui showing for users (Although not usable)

We planned to make changes to onboarding/popups to reduce them and add disable flags for certain parts, sadly this had to be delayed from this 2.1.2 release and will be in 2.1.3 later today or tomorrow
