Debugger: Fix team restart request.

UserInterface:
- Add Clone() function to set of required virtuals. This asks the subclass
  to create a new instance of its respective type.

{CommandLine,Graphical,Report}UserInterface:
- Implement the above function.

TeamDebugger:
- Add accessor for the currently active UI.

TargetHostInterface:
- Set correct request type when setting up the options for a team restart.
- Ask the TeamDebugger for its user interface and clone it in order to fill
  in that aspect of the debug options. This fixes a regression introduced in
  commit 880a64, which inadvertently resulted in team restarts no longer
  working.
