Specify MySQL storage engine for mfdb temp tables.
Since MySQL 5.5 changes the default storage engine to InnoDB, and since
many distros configure the InnoDB file path to refer to a directory on a
file system with barriers enabled, any temporary tables written to disk
will be written as InnoDB tables on the InnoDB file path, rather than
using MyISAM tables, which can be stored on the tmpdir.  This results in
severe performance issues when using mythfilldatabase with Schedules
Direct data.  Therefore, specify the use of MyISAM storage engine for
mythfilldatabase DataDirect temporary tables.
