setup.py has been removed, and Poetry is now used to package for
install. This fixed an issue i had with uploading to PyPI, so one can
now run 'pip install jellyfin-accounts' to install.
As many services don't support full encryption, there is now an
encryption option in the [smtp] section, allowing you to choose between
ssl_tls and starttls.
The admin page now has the option to send an invite to an email address.
Since there are now two email types (invites and pw resets), the new
sections have been added to config.ini, and email_template and
email_plaintext have been renamed to email_html and email_text
respectively.
