refactor: Decouple IrisGrid from Dh.Sort, use SortDescriptor instead

[vbabich]

• Decouple IrisGrid from Dh.Sort, delegate sort hydration to model to allow plugins use own sort API
• Allow negative column indexes in IrisGrid, so plugins could sort and filter on non-columns, such as ColumnBy sources

Just a question about the removed JS doc, looks good otherwise. Glad it's not a breaking change either!
