* Added missing MessagingCommandHandler methods.
* Added a class for handling "send message" commands and install by
default. At least in theory messages issued by the kernel should now
be delivered to the target. Still untested.
* Added lock to protect the command handler map.

* Added the class MessagingCommandHandler, instances of which can be
registered as handlers for specific commands sent by the kernel.
(Beautifully object-oriented :-)
* Fixed a bug regarding MessageArea creation (the object was deleted
twice on error).
* Actually resume the command processor thread.
* Turned the class into a singleton.
* Now always process all commands found in an area (should minimize
latencies).

Modulo bugs the class is now complete.

The beginning of the registrar-side kernel->userland messaging service.
The passing of commands from kernel to registrar should be complete now,
only the actual message delivery is missing.
Completely untested yet.
