scroll style

Like android's scroll bars. 像android的滚动条。Forked from onlywsx's extension. 移植自onlywsx的原扩展

Like a scroll bar in the android, activity display the scroll bar, usually when they don't show, don't take any extension process. 像android中滚动条一样，活动时显示滚动条，平常时则不显示,不占扩展进程。 =============================== 1.2.X update: add horizontal scrollbar. detect flash player in full window mode and hide this scrollbar.(experimental) update colors from material design guide. update jquery to be compatible with firefox. 注：原作者联系不上，代码是我私自更新的。非码农，bug修复极慢。╮(╯▽╰)╭
