[ic] Zero Dollar Shipping Results and the Shipping Tag

[Gary Norton]

For reference this catalog based off of the Mike04 Demo.

On a cart that returns zero weight (No Shipping Needed) the shipping tag is
not returning any <option> values.

This causes a single option with the text "Not enough info" to be placed on
the page. However, this is not a valid option and thus causes
mv_form_profile to fail.

What would be the best way to handle this event? 

Here is a snippet of the shipping.asc:
price_grnd:	Ground/Priority Mail    
	crit			weight
	min				0
	max				0
	cost			e No shipping needed!
	
	min				1
	max				119
	cost			8
	
	min				119
	max				239
	cost			10
	
	min				239
	max				359
	cost			15
	
	min				359
	max				479
	cost			18
	
	min				479
	max				599
	cost			20
	
	min				599
	max				9999
	cost			25


Here are applicable page code snippets:
