- Use autoloader, rather than just require PHP file (add all classes/interfaces as appropriate)
- Check if wfAkismetKlikObject() is properly unused, if so, remove
- Move hook functions out of Global Scope (part of task below)
- Convert to extension registration T98668
@Reedy: @Georggi1999 Hmm, should we keep backward compatibility? Now, AkismentKlik supports 1.19+ so we shouldn't remove this AkismentKlik.php code. Just keep it, and add extension registration. But in case we don't want to keep backward compatibility, we should remove all of these old registration code.
