- Added basic ping handling.

Browse Source 
Not sure what's up with the MC client, though. It doesn't seem to end up giving good results like the KA packet return is hanging and waiting for other things to process instead of being handled on its own to give a true result.

Feel free to update if there's any way to deliver truer results.
