Improvements for Private Chats from a Conference Room

• Acceptance Test - Add?:

  No

In a conference room invited users are different from the roster users (even if they are the same). It produces that:

1. Private chats without buttons (profile, send files, send pictures, dial) see conferenceAndChat.gif
2. Different history. History of private talks from a conference room is stored in a separated file and therefore if later I see the entire history of the person, I do not see chats that came from private chats.
3. Double click a chat member and I see the chat tab, double click the same member in the roster and open a new chat tab. It should be the same.
4. Strange names (conferenceAndChat.gif)
5. Warn while closing a chat window with a conference (Are you sure you want to quit the conference room?)
