missing browser support in readme

[Grawl]

I am trying to debug some site with verge as a basis for animations, and I don't know it's my code or it's verge. no errors in IE at all, but classes are not added on inViewport event.

So, in short: what browsers are supported by Verge?

[ryanve]

.inViewport, .viewportW, .viewportH should all work in IE6+

does that help?

@ryanve would you mind of making this information official? it might be helpful for developers to make sure if it is what they need. Does it work on iOS/Android? Any limitation running on IE? Thanks

Good idea to put that information in README.md! 👍
