 *
 * Each object in the `notifications` array defines a type of notification the
 * application will have with the following properties:
 *
 *  - `.label` name used to identify the type of notification being used (required)
 *  - `.dispname` name users will see in Growl's preference panel (defaults to `.label`)
 *  - `.enabled` whether or not notifications of this type are enabled (defaults to true)
 *  - `.icon` default icon notifications of this type should use (url, file path, or Buffer object)
 *
 *  Example registration:
 *
 *      growl.register('My Application', 'path/to/icon.png', [
 *          { label: 'success', dispname: 'Success', icon: 'path/to/success.png' },

 *  - `.label` type of notification to use (defaults to the first registered type)
 *  - `.title` title of the notification
 *  - `.icon` url, file path, or Buffer instance for the notification's icon.
 *  - `.sticky` whether or not to sticky the notification (defaults to false)
 *  - `.priority` the priority of the notification from lowest (-2) to highest (2)
 *  - `.coalescingId` replace/update the matching previous notification. May be ignored.
 *
 * If provided, `callback` will be called when the user interacts with the notification.
 * The first argument will be an `err` error object, and the second argument an `action`
 * string equal to either 'clicked' or 'closed' (whichever action the user took.)
