Ripple Client refactoring notes, May 6th 2013

Turning client classes into services/controllers

Old	New	Comment
`src/js/client/model.js`	`src/js/controllers/app.js`	The model stuff was moved to a global controller.
`src/js/client/status.js`	`src/js/controllers/status.js`	The status module is now a controller, see "Status controller" below.
`src/js/client/network.js`	`src/js/services/network.js`
`src/js/client/id.js`	`src/js/services/id.js`
`src/js/client/blob.js`	`src/js/services/blob.js`
`src/js/client/angular.js`	`src/js/entry/desktop.js`	Which modules are used might be target-specific, so the loading has been moved to `entry/`.
