added code to /updateraw route

not sure of full test requirements for update cycle, assumed from http://www.techempower.com/benchmarks/#section=data-r6&hw=i7&test=update they want to see a db query to get ran row, then a separate db query to update same row

otherwise this could be more efficient grabbing $queries of records in one query, looping thru that dataset, then writing the update in a transaction.

or I may be totally wrong.
