Fixed blog comment captchas

A customer pointed out that the “captcha” mechanism protecting this blog against spammers worked so “good” that even legitimate users couldn’t post any comments.

Embarassing. Turned out that the plugin providing this feature was indeed install wrongly. It broke after a system upgrade. Never change a running system!

This posting serves a “comments are open again” notice as well as a testbed for trying out the feature.
