Implement Sort for paged data display and large datasets

[RandomFractals]

See current paged data and sorting limitations in docs: https://github.com/RandomFractals/tabular-data-viewer#limitations

Paged data for large datasets was added in #60

Use sort table columns from view state config added in #64 to sort all the loaded data in table view instead of relying on Tabulator to sort data only for the currently displayed page.

Tabulator sortMode: 'remote' docs: http://tabulator.info/docs/5.0/sort#ajax-sort

[RandomFractals]

will provide the sort option for the whole dataset in the new pro version of data package explorer: https://github.com/RandomFractals/data-package-explorer
