* Just one settings file, now including auth settings
* people.js was *almost* a cleanly separated model layer, it did almost nothing with req and res. So I took it the rest of the way. All the routes are in app.js, except for that one route hanging out in index.js. See model/people.js. You could have a routes/people.js too if you wanted to get the routes out of app.js
* people.js has a proper constructor and exports a convenience function to call it, so we can inject the database properly when setting it up
dbConfig.js is obsolete
Oops, index.js still depended on dbConfig.js. I got rid of index.js because it was the only route honored with its own file. Later we might want a routes/people.js with all the routes relating to people or something. We'd want to set that up like people.js, with a proper constructor so we can pass it the settings and objects it needs
Moved the remaining direct uses of the db to manipulate people into model/people.js. We can now replace it at any time with Folger's Crystals or, say, CouchDB
Oops, the domain name wasn't visible to the model code. But we don't want a redundant settings. Solution: admin-editable settings belong in settings.js. Logic that massages the settings, for instance by copying the domain setting down into settings.db, belongs in config.js.
* Fixed the socket stuff. There is a socket object for every person who connects, so you have to keep them all around and send things to all of them. Also you need to authenticate sockets separately from regular stuff. Created a socketKey mechanism for that so we know who's talking. Explored and rejected a bunch of crappy mechanisms for this and created one that seems sound for our needs.
* Really really really basic chat! This is proof of concept but it's all socket.io which is very cool.
