Bug 20966: Add column configuration to table of orders in a basket

This patch adds column configuration to the table of orders in a basket.
It replaces the "Show all details" checkbox which previously was used to
show the hidden "tax included" columns. Now those columns are hidden by
default in the columns configuration file.

To test, apply the patch and view a basket with multiple orders. Test
all DataTables functionality (paging, sorting, filtering) including
showing and hiding columns.

Test with both an open and a closed basket.
