In BeamNG.drive, the configuration files use the proprietary standard "JBeam", which is very similar to JSON but with more relaxed rules. This C# function converts JBeam strings into JSON, so that they can be parsed and edited easily by some 3rd party JSON library. There's some lazy programming here that could be cleaned up, but I have since sto…

	//jbeam allows for newlines to be in place of commas. Who thought that was a good idea?
	//Replace any letter or number, or closing array (]) or dictionary (}), with 0 or more spaces between it (\s*?) and the newline (\n\r) with ITSELF, plus a comma, plus a newline

	//this fixes the case where we have 2 numbers next to eachother { ([0-9])[\s]+([\-0-9]) } outside of a quote { (""[^""]*?""|\Z) } and separated by AT LEAST ONE SPACE { [\s]+ }
