/*

	SAFE-MAIL-LINK FUNCTIONS

	usage:

	a mailto like this one:  
	<a href="mailto:someone@somehost.com">someone@somehost.com</a>

	(which is nice food for spambots..) has to be changed to 

	<a href="#" onmouseover="antispam(this, 'someone', 'somehost.com');">
		someone<span gid="hda">  </span>somehost.com
	</a>

	this way, there's no @ sign at all in the source.
	
	insert the following line in the head of every page that uses mailto links:
	
	<script src="safemailto.js" type="text/javascript"></script>	

	when the page loads the script puts an '@' sign in every found '<span gid="hda"> </span>',
	so that all mail links appear correctly.
