Wrap jQuery events and callbacks with try...catch blocks. Original code from: https://github.com/airbrake/airbrake-js/blob/master/src/notifier.js#L173
/*
* Add hook for jQuery.fn.on function, to manualy call window.Airbrake.captureException() method
* for every exception occurred.
*
* Let function 'f' be binded as an event handler:
*
* $(window).on 'click', f
*
* If an exception is occurred inside f's body, it will be catched here
* and forwarded to captureException method.
*
* processjQueryEventHandlerWrapping is called every time window.Airbrake.setTrackJQ method is used,
* if it switches previously setted value.
*/
