"Deprecated" Braintree_TransparentGateway causing error

[Forbin]

Braintree changed this file and they are trying to call a method statically that is not static.

"This is a known issue we are tracking down right now. See the post here: braintree/braintree_php#63
However, I would like to point out that TransparentRedirect is a very deprecated product and thus it will not support any new features or enhancements to the API. It’s also worth noting that our new solution, v.zero, relieves the same PCI burdens and has been seen to be more reliable than Transparent Redirect. Our support will also be much more responsive, as this product is being actively maintained and supported."
