Add onViewGoCommand to Home.js controller and reconnect Home.js and List.js controller references.

This commit reconnects the home screen with the rest of the app's
functionality by moving the onViewGoCommand into the new Home.js
controller. (onViewGoCommand sends the user to the next page in the
search process.) This commit also uncomments the home and listview
references in each controller to allow them to refer to one another.
Clean and repair listSpec.js tests

Prior to this commit, listSpec.js contained some outdated comments,
sanity checks and the onViewGoCommand test was hidden in a comment.
This commit removes these comments, sanity checks and unhides the
onViewGoCommand test with Jasmine's pending() feature.
Update onSetDistance test to use correct parameters and remove "#" from pending test.

This commit updates the onSetDistance test to no longer use the
undefined placeholder parameter 'thing' in listSpec.js and removes the
"#" sign from the onViewGoCommand description.
