=head2 connect_call_use_foreign_keys
Used as:
on_connect_call => 'use_foreign_keys'
In L<connect_info|DBIx::Class::Storage::DBI/connect_info> to turn on foreign key
(including cascading) support for recent versions of SQLite and L<DBD::SQLite>.
Executes:
PRAGMA foreign_keys = ON
See L<http://www.sqlite.org/foreignkeys.html> for more information.
