All DB columns are set to varchar, PHP 7.2 compatible fixes

All DB columns that had a varchar(number) are changed to varchar.
The edit_language default unique grouping has been removed because this
does not work (you cannot have unique on this when it is 1/0 flag only)

Update Output\Form\Generate and edit_base to be PHP 7.2 compatible with
removing all old while (list() ... each()) entries. Fix all undefined
counts, etc.

Login class update is long line wraps and clean up of some nested
teniary parts
