Changed delay to 1/10 sec

Because there's no reason to have it be half a second. Way too long,
even if it's unlikely to have two planes fly through in that time
period, it'd be nice to have it still trigger properly.
Added delay after initial triggering

After airplane goes through, added code to wait 20ms and then read the
sensor again. This is only 1/50 sec and should still catch all paper
airplanes, since there was code to check every 1/20th sec before and it
worked almost every time, but 1/50sec should be enough time to make sure
there's actually a paper airplane in the target, and not just a
momentary fluke of noise on the signal line or who knows what.
Changed double-check detector delay to 1/100th sec
