Feature Request: Add DataTable Checkbox Header Toggle All Pages Option

[saverett]

Add headerCheckboxToggleAllPages DataTable property to allow the header checkbox on paged DataTables with checkbox multiple selection enabled to toggle the selection of items across all pages. Previously this was only possible via the onHeaderCheckboxToggle event--however, doing so produced strange results where the header checkbox would remain checked even if only the current page's items were selected. This change provides the expected results. This is an improvement over the original fix provided in #1412.
Update demo/documentation to reflect new property.

I created a new property for this so as to not alter the previous behavior of the header checkbox on paged DataTables--however, if that isn't a concern we could simplify this and remove the new property by just having the header checkbox toggle the selection of all items across all pages as its default behavior (for paged checkbox DataTables).

This feature works with lazy load?

[saverett]

@lommez The table selection feature works by adding the elements for the selected rows into a selection array. Since not all elements are loaded at once with a lazy load table, this feature will not work with that configuration.

Thanks @saverett.
