Store the sort/filter state of jQuery-DataTables-enabled tables in hgSession and hgPublicSessions to the cart, without including that state in saved sessions.  Block IE versions before 11 from seeing the DataTables table version, due to checkbox issues.  Bonus: fix for a minor session deletion bug. refs #15312, #17509
