AlexRa 8a0c5d14d4 All (?) MySQL stores fixed to use DBGuid.FromDB()
This was needed if we want to update to the latest MySQL
connector dll.  It automatically converts CHAR(36) to
Guids, so getting them as strings no longer works.

By using DBGuid.FromDB(), we unlink from any particular
storage format of GUIDs, could even make them BINARY(16)
if we like.

Actually not all MySql units are touched, but the remaining ones don't
seem to be affected (they don't read GUIDs from DB)
