Subject: [PATCH] Update Cart.php

Fixed a bug where 0 is passed as the taxrate to the Cart:add facade resulting in it not evaluating right since '0' is not true in a if statement. Changed therefore the comparison to isset() so it rather checks if there is passed a taxrate of some kind. Also added in the if statement a simple check to see if the taxrate is numeric, and if not default to the one in the config
