Simple guestbook

A simple php/mysql guestbook application with minimal database usage and two-step acceptance process. Basic intended flow:

1. User fills out form.html.
2. create_comment.php uses data entered into form to create a URL which user has to access to confirm their entry (by default, the link is sent via mail using mail_templates.php).
3. config_comment.php verifies the entry data from URL params and forwards the entry to a moderator (again, the link is sent via mail using mail_templates.php), who makes the final decision (again, by accessing a link).
4. accept_comment.php verifies the accepted entry data from URL params and only then stores it in the DB.

form.html, as well as messages in send_confirmation_link and send_acceptance_link of mailer.php, are pretty minimal and intended to be edited.

config.php stores the DB access info and a secret used to generate links, while install.php can be used to create a table in the DB.

Caveat: some user-facing data is in Polish, because I can.
