Submits a HTML form as JSON

Created by Keith Hackbarth 2018 Based off idea by David Tomaschik https://systemoverlord.com/2016/08/24/posting-json-with-an-html-form.html

Example usage:

$("form").submit(function(event){event.preventDefault();submitAsJSON(this);});

Output is is the same action as the original form but with JSON data instead of form-urlencoded.

Worth noting that hack that enables this to function adds a dummy key value pair to JSON called trash
