Fix mutation event firing/response. Fixes #2530954 Major facelift of the Recordset internals. Strucutural, though; not performance related, really. The internal hash table is now properly initialized and updated in response to changes in the _items array. DataTable updated to listen for recordset:tableChange as a signal from its Recordset that the UI needs to be updated. Lots of code simplification.
