Another quick bug fix release, correcting problems caused by the recent upgrades.
- Exclude category option was broken. Fixed that.
- Searching for a non-existing category ID caused an error. Fixed that.
- Occasional blank screens of death occurred when multibyte string operations weren’t installed. That should not happen anymore.
- Fallback to OR search was a bit broken.
- Premium only: New users are automatically indexed, that didn’t work before.
