UIWebView Seamless Switch to Wkwebview

Wkwebview is the new web browsing view of IOS8

Advantage : Loading speed is almost one times higher than UIWebView, memory use above, but less half.

Disadvantages : Wkwebview does not support caching and Nsurlprotocol interception.

I recommend that if you use a page that is not high on the cache, the user experience will improve a lot.

Since the project was previously UIWebView and compatible with IOS8 before. So I created a new class Imywebview you can seamlessly upgrade to Wkwebview if you replace UIWebView globally.

The APIs in IMYWebView.h automatically support UIWebView and Wkwebview internally,

title,estimatedprogress is the new API that I think is more useful in Wkwebview
