support reading API docs on iOS devices

[jvasileff]

The iframe is not scrollable on iOS. Adding these css properties fixes it:

#wrap {
    -webkit-overflow-scrolling: touch;
    overflow-y: scroll;
}

There may be a better or more cross platform way to do this. These came from the first google search result I clicked on: https://davidwalsh.name/scroll-iframes-ios

Actually, I may have to remove that iframe entirely since I don't think I can make it work across domains :(

That page is gone.
