 *
 * jGrowl is a jQuery plugin implementing unobtrusive userland notifications.  These
 * notifications function similarly to the Growl Framework available for
 * Mac OS X (http://growl.info).
 *
 * To Do:
 * - Move library settings to containers and allow them to be changed per container
 *
 * Changes in 1.2.11
 * - Fix artifacts left behind by the shutdown method and text-cleanup
 *
 * Changes in 1.2.10
 * - Fix beforeClose to be called in click event
 *
 * Changes in 1.2.9
 * - Fixed BC break in jQuery 2.0 beta
 *
 * Changes in 1.2.8
 * - Fixes for jQuery 1.9 and the MSIE6 check, note that with jQuery 2.0 support
 *   jGrowl intends to drop support for IE6 altogether
 *
 * Changes in 1.2.6
 * - Fixed js error when a notification is opening and closing at the same time
 *
 * Changes in 1.2.5
 * - Changed wrapper jGrowl's options usage to "o" instead of $.jGrowl.defaults
 * - Added themeState option to control 'highlight' or 'error' for jQuery UI
 * - Ammended some CSS to provide default positioning for nested usage.
 * - Changed some CSS to be prefixed with jGrowl- to prevent namespacing issues
 * - Added two new options - openDuration and closeDuration to allow
 *   better control of notification open and close speeds, respectively
 *   Patch contributed by Jesse Vincet.
 * - Added afterOpen callback.  Patch contributed by Russel Branca.
 *
 * Changes in 1.2.4
 * - Fixed IE bug with the close-all button
 * - Fixed IE bug with the filter CSS attribute (special thanks to gotwic)
 * - Update IE opacity CSS
 * - Changed font sizes to use "em", and only set the base style
 *
 * Changes in 1.2.3
 * - The callbacks no longer use the container as context, instead they use the actual notification
 * - The callbacks now receive the container as a parameter after the options parameter
 * - beforeOpen and beforeClose now check the return value, if it's false - the notification does
 *   not continue.  The open callback will also halt execution if it returns false.
 * - Fixed bug where containers would get confused
 * - Expanded the pause functionality to pause an entire container.
 *
 * Changes in 1.2.2
 * - Notification can now be theme rolled for jQuery UI, special thanks to Jeff Chan!
 *
 * Changes in 1.2.1
 * - Fixed instance where the interval would fire the close method multiple times.
 * - Added CSS to hide from print media
 * - Fixed issue with closer button when div { position: relative } is set
 * - Fixed leaking issue with multiple containers.  Special thanks to Matthew Hanlon!
 *
 * Changes in 1.2.0
 * - Added message pooling to limit the number of messages appearing at a given time.
 * - Closing a notification is now bound to the notification object and triggered by the close button.
 *
 * Changes in 1.1.2
 * - Added iPhone styled example
 * - Fixed possible IE7 bug when determining if the ie6 class shoudl be applied.
 * - Added template for the close button, so that it's content could be customized.
 *
 * Changes in 1.1.1
 * - Fixed CSS styling bug for ie6 caused by a mispelling
 * - Changes height restriction on default notifications to min-height
 * - Added skinned examples using a variety of images
 * - Added the ability to customize the content of the [close all] box
 * - Added jTweet, an example of using jGrowl + Twitter
 *
 * Changes in 1.1.0
 * - Multiple container and instances.
 * - Standard $.jGrowl() now wraps $.fn.jGrowl() by first establishing a generic jGrowl container.
 * - Instance methods of a jGrowl container can be called by $.fn.jGrowl(methodName)
 * - Added glue preferenced, which allows notifications to be inserted before or after nodes in the container
 * - Added new log callback which is called before anything is done for the notification
 * - Corner's attribute are now applied on an individual notification basis.
 *
 * Changes in 1.0.4
 * - Various CSS fixes so that jGrowl renders correctly in IE6.
 *
 * Changes in 1.0.3
 * - Fixed bug with options persisting across notifications
 * - Fixed theme application bug
 * - Simplified some selectors and manipulations.
 * - Added beforeOpen and beforeClose callbacks
 * - Reorganized some lines of code to be more readable
 * - Removed unnecessary this.defaults context
 * - If corners plugin is present, it's now customizable.
 * - Customizable open animation.
 * - Customizable close animation.
 * - Customizable animation easing.
 * - Added customizable positioning (top-left, top-right, bottom-left, bottom-right, center)
 *
 * Changes in 1.0.2
 * - All CSS styling is now external.
 * - Added a theme parameter which specifies a secondary class for styling, such
 *   that notifications can be customized in appearance on a per message basis.
 * - Notification life span is now customizable on a per message basis.
 * - Added the ability to disable the global closer, enabled by default.
 * - Added callbacks for when a notification is opened or closed.
 * - Added callback for the global closer.
 * - Customizable animation speed.
 * - jGrowl now set itself up and tears itself down.
 *
 * Changes in 1.0.1:
 * - Removed dependency on metadata plugin in favor of .data()
 * - Namespaced all events
