- revert feature 564: log the login of each user; but add the possibility to be
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 git-svn-id: http://piwigo.org/svn/trunk@1744 68402e56-0260-453c-a942-63ccdbb3a9ee
