[Neos] Creating a New FlowQuery Operation

[Dmitri Pisarev]

Frankly I don't know what it does use for sorting now.
If you need particular sorting, you could do that via custom FQ operation,
but it's not very fast for large amount of nodes.
Sorting will be much easier soon, as there'll be a native way to do that
with FlowQuery.
