Update externs/chrome_extensions.js for some new methods in chrome.usb. * Add .getUserSelectedDevices, .getConfigurations, .getConfiguration, .setConfiguration * Add events .onDevicesAdded, .onDevicesRemoved * Adjust signature for .openDevice to match the description in the official web page.   (see http://developer.chrome.com/apps/usb.html#method-openDevice, the callback takes a   mandatory parameter) * Add classes for some types formerly described with a bag-of-objects but that now are   properly defined. This will necessitate corresponding changes in projects using these   methods:
