Added a WKWebView based example

[dodikk]

WKWebView does not need this POD to achieve the same thing.
Still, I think the example and a readme mention might be useful.

Based on #9
After merging that one, the diffs should become more brief.

The "foo/bar" example with basic authorization works fine in WKWebView.
However, my "video with authorization" example fails (while it works fine with UIWebView and this library).

I'll push more commits when I discover the correct settings for WKWebView.

Using an isolated non-persistent site data store pops up the alert for NTLM but that does not help the playback yet.

WKWebViewConfiguration* config = [WKWebViewConfiguration new];
    config.allowsInlineMediaPlayback = YES;
    config.allowsPictureInPictureMediaPlayback = NO;
    config.mediaTypesRequiringUserActionForPlayback = WKAudiovisualMediaTypeAll;
    config.websiteDataStore = [WKWebsiteDataStore nonPersistentDataStore];

Never mind, the video's URL scheme was http which is "banned" by default due to Apple security policy. So that the exceptions should be added explicitly.

Alternatively, JavaScript injection could be used if the server can serve videos via https. For example, https://gist.github.com/dodikk/e028c03cd809271c950c135a3abd4240

The config.mediaTypesRequiringUserActionForPlayback = WKAudiovisualMediaTypeAll; and Deployment Target >= iOS 10.0 are impactful as well. Without those options the legacy project did not play the video while the prototype from this pull request did work.

Very minor request.

I don't think you should bring JAHPAuthenticatingHTTPProtocolDelegate into this at all. It isn't needed.

Deleted the mentioned #pragma mark

Will be merged as part of a more recent PR #11
