/**
 * Send growl notification _msg_ with _options_.
 *
 * Options:
 *
 *  - title   Notification title
 *  - sticky  Make the notification stick (defaults to false)
 *  - priority  Specify an int or named key (default is 0)
 *  - name    Application name (defaults to growlnotify)
 *  - sound   Sound efect ( in OSx defined in preferences -> sound -> effects)
 *            works only in OSX > 10.8x
 *  - image
 *    - path to an icon sets --iconpath
 *    - path to an image sets --image
 *    - capitalized word sets --appIcon
 *    - filename uses extname as --icon
 *    - otherwise treated as --icon
 *
 * Examples:
 *
 *   growl('New email')
 *   growl('5 new emails', { title: 'Thunderbird' })
 *   growl('5 new emails', { title: 'Thunderbird', sound: 'Purr' })
 *   growl('Email sent', function(){
 *     // ... notification sent
 *   })
 *
 * @param {string} msg
 * @param {object} opts
 * @param {function} callback
 * @api public
