Make sure that BaseWorker deletes the thread when is finished.

Implemented ClientManager so it can manage the usb and wireless threads.
Impelmented better mutex logic on CmaClient.
Execute the cma events in a different thread so the event listener is
available.
Code refactoring.
Fix memory leaks in threads.
Updated readme.
