Subject: [PATCH] Only disable keyboard focusing for touch devices [Fixes
 #1541]

This fixes the issue [1] by first checking to see if the current
device is a touch device.  The other issue [2] that occured because
of the original fix [3] is now fixed, because the hidden inputs
are always focused by default on non-touch devices.

The code used for detecting touch devices was pulled from
StackOverflow [4].  Information on the reasoning behind this fix
can be found on GitHub [5].
