jQuery Autosave

Tracks the state of a form and calls an autosave action when things change.

Option:	Default:	Explanation
url	undefined	When undefined, the autosaver will call the form's action in an ajax request. If you define this method you should either specify a URL for the ajax method or a function, like function(e,o,callback) {} which handles the autosaving action.
interval	60000	The interval at which the autosaver should fire off a save action at.
monitor	3000	The interval at which the autosaver should check the form to see whether or not it has been dirtied.
setup	function(e,o) {}	Callback when the autosaver is setup.
record	function(e,o) {}	Callback when the autosaver records the state of the form.
save	function(e,o) {}	Callback when a save event is fired off.
shutdown	function(e,o) {}	Callback when the autosaver is shutdown.
dirty	function(e,o) {}	Callback for when the autosaver finds dirtied data.

Additionally it is worth noting that if you include the class autosave-ignore on any form node that node will be ignored by the autosaver.
