Remove ORDER BY.

Queries fail with out of disk space error for very large databases.
Added --tped to query and --tfam to dump.

--tped as an option to query will output the results
of the query in transposed ped (TPED) format.

gemini dump --tfam will dump out the sample information
in TFAM format.
