Apparently the secret property on a singleton hidden in the guts of
SQLAlchemy has been made private recently, so what I wanted to do (get a
list of all ORM classes) is now impossible. I gave up on trying to find
a real solution and just slapped together something using dir().
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.
