done by a plugin
- create a "standard" way to define PHP functions that we use but might not be
available in the current php version
- when a comment is rejected (spam, anti-flood etc), put the content back to the
browser in case there is a real user behind it
- now a comment can be entered only if the page was retrieved between 2 seconds
ago and 1 hour ago
