Add a check for boundary rules for QUERY (tornado)

    QUERY requires that the request variable for number of queries be
    bound between 1 and 500; anything less than 1 should result in 1
    result and anything more than 500 should result in 500.

    If the test does not clamp the request variable as such, then it
    fails validation.
Merge branch 'master' of https://github.com/TechEmpower/FrameworkBenchmarks
return a list even for a single query #742
update 'query_url' to '/queries' instead of '/db', now
'Single database query' and 'Multiple database queries' use
different handlers.
Merge pull request #742 from apieceofredcloth/master
