ContactList menu in tab mode has all action visible. Icons added to status change and close all chats.

ContactList fragment placed in layout statically (not created via FragmentManager from Activity code).

ChatViewerAdapter simplified: "intent" chat taken from ChatManager. No need to recreate adapter to open new chat.

Message Notification: backstack removed (ContactList always called first now);
ContactList: action set to null if chat related action; "send to" action call chat (but no text so far).

ChatScrollerActivity is basic for ContactList and ChatViewer.
All chat intents received by ChatIntentActivity (base for ContactList), ChatViewer called from ContactList if needed.
More stable, but lack of functions (send/alert intents, etc).
