/*
Description:

	Allows only valid characters to be entered into input boxes.
	Note: does not validate that the final text is a valid number
	  (that could be done by another script, or server-side)

Usage:

	$(window).load(
		function()
		{
			$(".numeric").numeric(); // or $(".numeric").numeric(",");
		}
	);

Parameters:

	decimal     : Decimal separator (e.g. '.' or ',' - default is '.')
	allowPaste  : let paste operations through (does nothing with IE - paste is always allowed)
