Fix mobile BUG by blocking Touchstart event

Under IOS10, even user-scalable=no that have the META tag set cannot prevent users from scaling.

The workaround for this BUG is to block PC events:

function (EV) {    ev.preventdefault ();});

In addition, this method can also solve the iOS10 in the horizontal page overflow, even if the body set the Overflow:hidden still can slide the problem.

However, when this event is added, the iOS10 Rubber band effect is blocked and the text check feature is disabled.

This bug is resolved by blocking the default event for Touchstart, and also by blocking this default event to resolve the 300ms delay.

Of course, because the default behavior is blocked, the default jump page for a-label link cannot be implemented, only by manually adding events:

function (EV) {    = "www.tirion.me";});

The input box gets focus also needs to be resolved manually:

function (EV) {    ev.stoppropagation ();});
