Added a few classes to the debug kit:

* BDebugMessageHandler: Interface with hooks for handling of debug messages.
* BDebugContext: Essentially a C++ wrapper for struct debug_context, with
  handy methods for controlling a debugged team.
* BTeamDebugger: Proxy for a debugged team. Derived from BDebugContext.
* BDebugLooper: Wraps a main debug message loop. Any number of BTeamDebuggers
  can be added and associated with BDebugMessageHandlers.
