Immediate Interpreter: Tap to click improvements

After a lot of testing from ryant@, we've settled on these tap to
click improvements: Decrease tap timeout from 200ms to 100ms, prohibit
all taps within a border of the touchpad, and increase the existing
palm detection border.

BUG=chromium-os:23732
TEST=unittests pass, verified spurious taps from ryant's logs are
suppressed.
