Actually make http requests

• Define an interface for an http dependency
• Implement with node http (browserify will wrap XMLHttpRequest)
• Implement with angular $http

Need to define a common API that Node.JS and Angular and regular frontend javascript can interface with. I think based off of q makes sense because angular already uses this and it can wrap callback based API's nicely (Node.JS http/https modules).

A first step would be an injectable http client dependency that clients could set up however they pleased. Something like:

Using angular:

module.service("lightblueData", ["$http", function($http) {
  var http = lightblue.http.ng($http);
  return new lightblue.DataClient(url, http);
]});

Using node / browserify:

var lightblue = require("lightblue");
var http = require("http");
var httpOptions = { 
  // setup auth options or w/e
};

var data = new lightblue.DataClient(url, http, httpOptions);

.... something like that. May need a config object with angular too for auth setup or other(?) setup.
