window.Touch no longer reliable differentiator

Console logging was previously disabled for tablets and phones (for
reasons I no longer recall) using `window.Touch` to distinguish them
from other platforms.  This is no longer a valid distinction since
non-phone / non-tablet browsers are beginning to expose the name space
regardless of whether the host envirionment supports touch events.
