jquery .on('donetyping;, callback) integration

jquery.donetyping.js

// $('#element').on('donetyping', callback)
// Fires donetyping event when a user has finished typing. This is determined by the time elapsed
// since the last keystroke and timeout parameter or the blur event--whichever comes first.
//   @callback: function to be called when even triggers
//   @timeout:  (default=1000) timeout, in ms, to to wait before triggering event if not
//              caused by blur.
// Requires jQuery 1.7+
// Based on the jQuery extension created by @brad-christie on StackOverflow
//
