Please add support for IrcUser lastAwayMessage(Time) field as part of the LongTime feature
The fixed implementation in the core (https://github.com/quassel/quassel/pull/357/commits/fd84a0b221b9e1ae7789d9b134bc9d78996ae02b) changes the variable to the QDateTime type, renames it from lastAwayMessage to lastAwayMessageTime to make the name consistent with the other QDateTime fields in the same class and make it easier to implement backwards compatibility in clients.
It also looks to me like some work may need to be done to handle the field correctly for object deserialization during connection initialization, but I couldn't figure out for sure how that is handled so I'm not absolutely sure.
