Avoid attribute API methods in render loops There were a lot of calls to get('attr') within the row and cell rendering loops. The render methods should not be modifying these values during iteration, so it should be safe to capture the values before iteration. Similarly with the determination of cell formatters, all conditional logic and setup can be moved above the row render loop. This should speed up rendering somewhat (see ticket #2530152), though the biggest performance win will be moving away from Node.create to innerHTML string concatenation. That won't happen until 3.5.0. Also while I was in there, I moved UI related event bindings to bindUI and did some other code cleanup.

Replace the Recordset records, not the Recordset Fixes #2529872 onDataReturnInitializeTable was replacing the Recordset instance managed by the DataTable rather than just replacing its records. Since a fair amount of functionality is tied to the Recordset, this broke stuff.

Caption is optional. Fixes #2529968 A more comprehensive solution is warranted. At least one that doesn't incur the overhead of creating a caption element even if it's not used. I'm leaving that to the rendering performance pass.

Use valueFn for recordset attribute default value Fixes #2529980
