Fuse two copies of LeafPlanningIT and move them to the right place (planner.logical)
Add basic support for WITH to Ronja

o Support for handling some forms of WITH in SimplePlannerQueryBuilder
o Support for planning tails in QueryPlanningStrategy
o Add QueryPlanProducers for sort, skip, limit, projection
o Add/Update QueryPlanProducers: planApplyTail, planArgumentRow, planQueryArgumentRow, planSingleRow
o Make above query plan producers update the tail if the query graph has a tail
o Make projection + sortSkipAndLimit use QueryPlanProducers
o Visitor support for PlannerQuery
o SingleRow now keeps type info for building the correct SymbolTable in NullPipe. This should go away later.
Make SimplePlannerQueryBuilder produce complete QueryProjection instances instead of gradually building them
Fix wrong error message
Remove NoProjection
