Add GSM conference calling to simulator.

This CL adds a new item to the simulator menu:
  - Add GSM conference

The GSM conference action creates a conference with 5 phone calls.
Users can individually separate or kick calls out of the conference. Hanging up the second last call finishes the conference.
