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
Shared cookie storage support and other enhancements
- Although copying the NSMutableRequest does not return immutable copy, modified code to make copy instead of returning explicitly mutable copy so as to not mislead future developers.
- Code hygene
- Removed unnecessary log statements
Merge pull request #4 from SpencerP/develop
