Description

Currently selector identifier lookup directly uses Message::getProperty(). This is implemented by iterating over every property of the message and seeing if it is the property we wanted. So we end up iterating over all the properties for every identifier we lookup.

We really only need to do one iteration and we can save away every property we find for ongoing use in looking up selector identifiers.
