Implement support for displaying nickname changes.

This implements Swiften API for changing nicknames in MUC and correctly detecting nick name changes. In addition Swift now displays nickname changes as such and not as join/leave of a user. In addition, handling of nickname changes is integrated in ChatsManager and ChatControllers so that they are forwarded to PM chats of MUCs. Test-Information: Added unit tests for change of own nickname and nickname changes of others. Tested correct detection of nickname changes in a MUC with a Psi user changing its nickname and Swift correctly detecting and displaying it. Change-Id: I3287ba6ceeccd3be5cfb591acd6f88bffc9a43b2
