The Sqlite3 branch no longer includes the 'subscribe_noconfirm' configuration option.

Looks like an anti-spam update that was applied to Sqlite3 branch. The update forces users to opt in (ie. removed admin option to 'not require optin') and limits the number of 'new comment' emails to be sent if the opt-in link in the email is not clicked. It automatically stops sending comments after the first 3 unless the optin link is clicked.

Note: The 'subscribe_noconfirm'  **incorrectly still exists in the consolidated version** in files: `conf/default.php` and `conf/metadata.php`.

They need to be removed, but they will do no harm as the setting is now ignored.
