Fix to ignore elements that should be excluded

[agoel96]

There's an issue in the fc_hash_html() function to not honor the cart_excludes. For example, "cart" value should not be hashed along with a number of other values defined in the array $cart_excludes. However, this function does check the name/value pairs against the array.

If you add the following code at LINE 221, this will fix the problem.

// Skip the cart excludes
if (in_array($prefix.$name[2], self::$cart_excludes) || in_array($prefix.$name[2], self::$cart_excludes_prefixes)) {
self::$log[] = 'Skipping the reserved parameter or prefix "'.$prefix.$name[2].'" = '.$value[2];
continue;
}
