Title: Hole punching for Magento Enterprise FPC

When using Magento Enterprise's full page caching, the tagging elements are being cached. While this is not a problem for most tagging elements, the cart and customer tagging can get cached and therefore be transfered between customers. We saw the results of this when one of our clients got word from his customers that they were sent other people's carts in the "abandoned cart" emails.

This fix punches holes in the cache, so that the Nosto customer and cart tagging elements will always be up to date, and not cached between sessions.
