Add a spamc library for SpamAssassin.

Usage:
load("spamc.js");
msg=new SPAMC_Message(mesage_body);

/*
 * Simple checking...
 */
result=msg.check;
if(result !== false) {
	if(result.isSpam)
		// Handle SPAM here
}

/*
 * Process (update the message body)
 */
result=msg.check;
if(result !== false) {
	write result.message to file
}
