[TIMOB-1547] iOS: Events not working during view animation

While a view is being animated, it does not respond to click events (probably other touch events as well). Here's a sample app.js to reproduce:

var win = Ti.UI.createWindow({backgroundColor:'#fff'});

var view1 = Ti.UI.createView({ width: 60, height: 60, borderRadius: 30, top: -60, left: 0, backgroundColor: "red" });

win.add(view1);

view1.animate({top: 300, duration: 5000});

view1.addEventListener("click",function() { alert("working") });

win.open();
