Simon Willison b75edf4b30 add_foreign_key() accepts compound keys, composite FK indexes, refs #594
table.add_foreign_key() and db.add_foreign_keys() now accept lists of
column names to create compound foreign keys:

    table.add_foreign_key(
        ["campus_name", "dept_code"], "departments"
    )

Omitting the other columns uses the compound primary key of the other
table. Duplicate detection compares the full column lists.

db.index_foreign_keys() now creates a single composite index across the
columns of a compound foreign key, rather than an index per column.
