P3: Somewhat important Add the same convenience API's to Contact and Organizer API when working with tags.
Original change request included the following suggestion
Probably something like: QSet<QString> QContact::tags() const; void QContact::setTags(const QSet<QString>& tags); // also probably worthwhile void QContact::addTag(const QString& tag); void QContact::removeTag(const QString& tag); // also possible bool QContact::hasTag(const QString& tag) const {return tags().contains(tag);}
