Increase gesture completion delay for falsing.

The FalsingManager was hitting a race condition with View click
listeners, where clicks would still, somtimes come in after the
FalsingManager had already marked the gesture as un-analyzed.
Increasing the delay from 50ms to 100ms should all but prevent that
from happening.

I have also decreased the penalty for unalayzed taps since
accidentally tapping on the wrong part of the screen is not unlikely.
