Generic iFrame doesn't scroll on iPhone Chrome

[chameides]

This is a great service. Thanks for setting it up. Using Chrome on an iPhone5, I'm not able to get the generic iFrame to scroll, which is a problem if the iFrame content is larger than the iFrame.

It might help to add something like this:

@media screen and (-webkit-min-device-pixel-ratio:0) and (max-device-width : 1024px) {
#genericpreview .embed-container{
-webkit-overflow-scrolling: touch; /iframes should scroll/
overflow-y: scroll; /iframes should scroll, but this rule will cause two scroll bars in chrome on windows/
overflow-x: scroll;
}
}

I'll submit a similar pull request.
