Patch to increase TimerQueue rate

This patch changes the TimerQueue rate from 12 to 8ms on my system.  It fixes
crackling output from my interactive mmdevapi render tests, as mentioned in
comment #128.  You guys watching bug #28856 and bug #28282, please try it out.

CreateTimerQueueTimer vs. winmm timeSetEvent.
The difference is, winmm:time* uses:
    delta_time = timer->dwTriggerTime - GetTickCount();
thereby readjusting to elapsed time.  CTQT doesn't:
    queue_current_time() + t->period
deviating more and more.  We need tests to check whether that is correct CTQ
behaviour.
