Fixed namespaced classes and removed overflow hidden on root element

This probably not good to use a such common class as `container` because it's used for other purposes in other bigger frameworks. Also removed `overflow: hidden` because the `container` already strip the overflow and added `window.jQuery || window.Zepto` you only add a small polyfill for inner/outer(Width|Height) to make it work.
I think it's safe to remove all namespaced events. Instead of pin point every one.
