Fixed getting started tutorial by adding good-console reporter

Hi,

I got an error while trying to follow the plugins example in your getting started tutorial:

	.../node_modules/good/node_modules/hoek/lib/index.js:663
	    throw new Error(msgs.join(' ') || 'Unknown error');
	          ^
	Error: Invalid monitorOptions options reporters is required

Fixed it with explicitly adding reporters when registering the good-plugin.
