Using require rather than initializePlugin since the latter doesn't currently support a callback for tooltips

* Added validation to the view require to ensure a site key is even able to save an annotation
* For the POST handler to respond without processing a view
* Removed the PHP processed JS files (added inline js to php files to compinsate)
* Stopped using wdn.js and instead just use a CDN copy of jQuery (it's all that's needed)

Fix the insert/update/save issue related to not having an empty 'id' (or some other) key in new records that can be checked in the Record::save method, now explicitly call insert/update based on annotation existing

Height/width of the textarea in the iframe isn't available on document.ready/window.load so use a setTimeout as an ugly fix; Some css changes for better webkit styling

Create a view to handle a page that will serve as a pop-up login form should an unauthenticated user see an annotation box

Don't throw a 404 exception if the requested annotation doesn't exist, want to still display the ("empty") html textarea for that nonexistant annotation to let the user create it;  (Should the exception handler somehow pump out the empty textarea html???)

remove all the functionality from editing wdn_annotate since the content to be editted will now come from an iFrame.
