It used to abruptly abort if a csv file were missing, which wasn't very
nice when I'd just added a new table definition and was trying to reload
everything else.
Now it prints a status per table while loading, and will declare missing
tables to be... missing.
Tables weren't being defined as UTF-8 if that wasn't the server default.
A lot of tables were trying to create erroneous auto_increment columns.
Foreign key checks were pretty much fucking everything up.
