Order the unread conversations in top of the contact list

Even if I have the unread switch deactivated, I will prefer to be able to choose if the new unread messages can go on top of the rest of the messages (ignoring the teams, messages etc). Just put on top all the chats where I have new messages.

This is because all the unread messages are spread all over the list I have in left side of the UO window and it is possible to skip some messages, especially if the list with the favorites is pretty long...
