Add as an ailias to the "Add Multiple Columns", a data table message called "Insert Columns"

[txnelson]

Adding an alias to the "Add Multiple Columns" message, would allow for a smoother transition from the Interactive functionality of the "Insert Columns" selection.  It would also be nice to add new functionality to the "Add Multiple Columns" to add n number of columns before each selected column.  Something like

     <before first|after last|after(column)|before each selected>
