QTimer support chrono literals

Hi,

This works.
QTimer::singleShot(std::chrono::milliseconds(1000), []

{ qDebug() << "1 second passed"; });

This is not supported:
QTimer::singleShot(1s, []{ qDebug() << "1 second passed"; }

);

This uses the chrono literals (new since C++14), more on that here: http://en.cppreference.com/w/cpp/chrono/duration

Could support for these literals be added to the QTimer methods where one provides time (start, singleshot, setInterval). Big plus for also providing a getters (remainingTime, intervalAsDuration and in QElapsedTimer::elaped) as clock ticks. That would allow a chrono duration_cast to any of the chrono supported times.
