* - `.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: 'warning', dispname: 'Warning', icon: 'path/to/warning.png', enabled: false }

* Send a notification with `text` content. Growly will lazily register itself

*
* A notification can have the following `opts` options:
*
* - `.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.)
*
* Example notification:
*
* growl.notify('Stuffs broken!', { label: 'warning' }, function(err, action) {
