Qt/SQL - Get column type and name from table without record

QSqlDriver::record() takes a table name and returns a QSqlRecord, from which you can fetch the fields using QSqlRecord::field().

So, given a QSqlDatabase db,

1. fetch the driver with db.driver(),
2. fetch the list of tables with db.tables(),
3. fetch the a QSqlRecord for each table from driver->record(tableName), and
4. fetch the number of fields with record.count() and the name and type with record.field(x)
