Add text reason to forced logouts/disconnects

This is in reference to http://n2.nabble.com/Banzai-example-question--tt364931.html#a364932 thread

If the sender has SendingTime accuracy issues, QFJ just disconnects the session but the sender doesn't see any detailed "reasons" for why that happens.

Would be nice to see a reason for a sending time accuracy disconnect, along with others such as "multiple connections from same senderCompID".
