[ic] Force a payment method at checkout for some items

It would be better to have a "cod_allowed" field in pricing or inventory.

This is a typical need of tying the database to the shopping cart
to test for shipping/pricing alternatives. IC has some facilities
that make it fairly easy to do it.

Add a column to the inventory database (or anywhere you choose) named
"cod_allowed". Set it to 1 if COD is allowed, blank otherwise.

In catalog.cfg:

	AutoModifier  inventory:cod_allowed

(Of course you restart/apply changes, having changed configuration.)

Now there will be a cod_allowed attribute in the shopping cart. At that point,
you can do:

	[calc]
		$Scratch->{allow_cod} = 1;
		foreach my $item (@$Items) {
			next if $item->{cod_allowed};
			$Scratch->{allow_cod} = 0;
			last;
		}
		return;
	[/calc]

Now you can test for your allowed payment methods:

[if scratch allow_cod]
	# ITL you need to enable COD
[/if]
