needed to add some service from CORE in hello_tutorial/run/hello.run

[Paul Dufresne]

Before it works, I had to add these lines:
		<service name="RM"/>
		<service name="CPU"/>
		<service name="IO_PORT"/>
		<service name="IRQ"/>
inside <parent-provides> section of hello.run.

I would have tought however that:
	<default-route>
		<any-service> <parent/> <any-child/> </any-service>
	</default-route>
would have made it optional, which was not.
