Added more thread control to developer shell

The method yield is now available in the context created for threads in the developer shell.

Added options --preemption/--no-preemption and --preemption-interval to control preemption in the developer shell when running several threads. Default is still to enable preemption with interval 1ms if threads are created.

I would really prefer it if this gave some indication to the user when parsing
the integer failed.
