<remarks>
	This function modifies "vardata" well beyond its original limits to contain
	information on the structure of the enum used to define "val".  This code
	uses the name and size information passed in the additional parameters as
	strings, and makes assumptions about how the compiler lays out memory to
	combine all the passed strings in to one big string in what could be ROM,
	but in SA:MP isn't.  This takes a human readable(ish) description of the
	array elements and converts it in to a much simpler to read format for the
	computer to use later when loading and storing data.
