Add focusableInTouchMode to widget labels

See http://crbug.com/29344 for an explanation of why this is necessary.

Note that I have not actually tested this proposed change. On Chrome, it appears to be necessary to set it in Java rather than xml (TextView.setFocusableInTouchMode()), but I'm not sure why.
