If all checkboxes are unchecked when a multifield is saved, the settings are now properly saved #11

Fixes #10

Adds a hidden field to all multifield checkbox field groups, with a reference to the field group ID.

Adds a hook on pre_update_option_{$option} from option.php to the function multicheck_empty_validation().

Adds the function multicheck_empty_validation() that handles validation of whether a multifield field group was empty (all unchecked) or not. If empty, ensures that the value is still updated to an empty array.

Sorry it took so long for me to notice! Can you submit the same bug to the actual S214-Settings library repo? That's an upstream bug more than a bug in Username Changer.
