Changeset 172

Message:

Added ClientIconified? and ClientDeiconified? events. Used these for an experimental tool to trace the subject lines of clients, typically instant message programs, to be able to monitor them even when they are iconified. Should be moved to a real module when it gets a better name and maybe a bit more configurability. Will probably wreak havoc on my productivity, too.
