The new jellyfin_login and admin_only allow anyone use their username and
password from jellyfin to login to the admin page, and restrict this to jellyfin
admins only, respectively.
Pressing the user settings button brings up a list of all jellyfin
users, and allows you to add or change their stored email addresses.
Additionally, changed emails.json to use user ID instead of username.
The program automatically converts the file to the new format at start.
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.
Invites and the generate invite form are now displayed as cards. Invite
codes are displayed in a monospace font so they are always aligned with
eachother. The delete button is now inline with the rest of the text.
Fixed an issue where some criteria on the form page wouldn't change to
red or green when one set one of them to 0 in the config. Also added a
lowercase option.
Added an extra debugging message to tell the file being read for a
password reset, and changed watchdog form using 'created' events to
'modified', otherwise there may be issues where the file is read before
it is fully written.
Password validation added, configurable under the [password_validation]
section in config.ini. Each criterion is displayed next to the form, in
red or green depending on whether the password passes it. form.html now
looks different because of it, whether it is enabled or disabled. An
error message is now displayed if the user already exists.
Changed admin.js so that instead of deleting all invites and then
generating them, new ones are created, pre-existing ones have their
expiry updated, and newly invalid ones are deleted. Accidentally
improved their layout, as well.
