Fixes for Issue#54.

[shanmuha]

Fixed the described issues - moved private resource-style function to ring.util.resource for getting resource files as stylesheets.
dump would also return html5 now.
Ring keys updated to added ssl-client-cert as well.

All tests pass and also tested using a dummy ring app using handle-dump.

Thanks for the code. There are a couple of things that need to be fixed, though:

The style-resource function should remain private, even if that means duplicating it in two namespaces. Hiccup is an implementation detail, so Ring should not expose Hiccup-specific functions in its public API.

You also have a bunch of upstream merge commits. You'll need to remove those, I'm afraid, and it might be an idea to squash your remaining commits into one.

Finally, I think we should avoid specifying the content-type as a meta tag, and instead just add the right header to the response (as the stacktrace middleware does).
