Support global Fluid ViewHelper namespaces (TYPO3 ≧ v8.5)

A really nice feature was introduced in the TYPO3 core during the last days of October '16: https://github.com/TYPO3/TYPO3.CMS/commit/d9e7b6a8eb445aceb6934f8f97691e2c433d0cae

Could that be supported by the Fluid Plugin?

(Feels as if it always becomes more complicated...)

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
