解除一些网站利用【user-select: none;】禁止复制的限制！

var array = document.getElementsByTagName("*");
for (var i=0; i < array.length; i++) {
    array[i].style.cssText = 
    \'-webkit-touch-callout: all;\' + 
    \'-webkit-user-select: all;\' + 
    \'-khtml-user-select: all;\' + 
    \'-moz-user-select: all;\' + 
    \'-ms-user-select: all;\' + 
    \'user-select: all;\'
}
