Status message fix, copy timestamp in assigmnet operator

* the timestamp of status message was not copied, so every time a status message was sorted or otherwise assigned the ts got lost or wrongly assigned.
* this meant the log messages were in wrong order, leading to very confusing results in the log screen or file.
* also added new timestamp formatter
* new function "BlackMisc::CVariant displayRole(const PQ &pq) const" which can be used if the PQ is already available
