Refactor Network ... AP Collapse function traces back + related issues.

[RobMackie]

routes/network.js::hotspotState fails because "network" object is undefined.
var network = require('../updater').networkManager;

fails to create a network object.

Examination of /fabmo-updater/updater.js shows that every references to networkManager has been commented out. I believe it was commented out when Ted brought the updater back into service. I think the network management functions of the updater have never been coded to work on the pi, only on the edison image.

Need to decide if it's something we fix or eliminate. the line "var network = require('../updater').networkManager;" appears in the routes/network.js file 11 times which means that object is needed at least in that many places.

Also, it seems bizarre to create the object in each function rather than at the module level.

Move on to removing network functionality form updater (except perhaps for reporting) -- and continue refactoring.
Having committed to the Pi, networking is primarily handled in the image setup rather than by FabMo.
