...onfiguration from the grunt file

Hi eric,

while running multiple node apps and wanting to debug them, I found that I couldn't set a debug port through the configuration in the grunt file. After investigating I found that the grunt task doesn't pick up the port - just whether debug is set or not.

I couldn't see any tests for the debug settings - so wasn't sure where to put the test for this, or indeed how to test this. If you'd like a test, please suggest where to put it and perhaps how best to test it.

I'm eager to merge this down, but I'm not quite...sure what it does? @edsykes Can you add an example of this in the project's Gruntfile.js? That'll help serve as a test, kinda how I have now for custom ports:

• grunt-express-server/Gruntfile.js

  Lines 104 to 109 in 742e7a8

  	custom_port: {
  	options: {
  	port: 8080,
  	output: "Express server listening on port .+"
  	}
  	},

• grunt-express-server/Gruntfile.js

  Lines 58 to 60 in 742e7a8

  	custom_port: {
  	src: 'test/custom_port_test.js'
  	},

• grunt-express-server/Gruntfile.js

  Lines 165 to 167 in 742e7a8

  	'express:custom_port',
  	'nodeunit:custom_port',
  	'express:custom_port:stop',
