Added the Sys.read() method which reads a specific type of data from standard input into a list of var refs;

Example:
	Sys.read(Number, \var x, \var y);	# reads two numbers into x and y
	Sys.read(Bool, \var true_or_false);	# reads a boolean value
	var str = Sys.read(String);		# reads and returns a string value
