Qt: Add missing multi-field column validation

GTK already has it, but Qt forgot about it, so multi-field custom column
works ok if previously saved in GTK-shark. Invalid validation prevent from
modifying and saving multi-field custom column in Qt version.

While at it, rename "custom field" to "custom fields" to ensure
we think about multi-field custom column.
