Shared cookie storage support and other enhancements

    - Added cookie injection to RZPWKWebView that will soft-inject cookies from NSHTTPCookieStorage into the DOM. This will sync WKWebView cookies with UIWebView cookies as much as possible.
    - Added request property
    - Set scalesPageToFit on UIWebView to mimick WKWebView functionality
    - Set dataDetectorTypes property on UIWebView to detect all data types
That's baffling. If you're still making changes for the pull request, please amend the comment to call this behavior out explicitly.
