CreateAllTables generates incorrect SQL when using uint32 as primary key

[rickb777]

If a struct has an unsigned ID, then CreateAllTables generates incorrect SQL. E.g.

type Person struct {
    Id               uint32
    Name             string
    Created          int64
    Updated          int64
}

The trace statement says

gorptest: 20:28:16.303405 create table if not exists `person` (`Id` varchar(255) not null primary key auto_increment, `Name` varchar(255), `Created` bigint, `Updated` bigint)  engine=InnoDB charset=UTF8; [[]]

So a varchar(255) has been incorrectly substituted instead of the 'int(10) unsigned' that would be expected.

The same problem applies with uint and uint64 too.

It also seems to happen with all uint, uint32 or uint64 fields, regardless of whether they are primary keys.

The problem seems to be caused by MySQLDialect.ToSqlType not including a more complete set of reflect.Kind cases.

This is fixed now and tested across the 3 supported databases.
