Summary:**Motivation:** In my app, I'm using a WebView that loads content from my mobile site. What I want to do is when a user presses a link on the loaded page, I want to stop the WebView's request, hijack the URL and open the URL in a new WebView, pushed to the top of the navigator stack. To me, this gives the overall app a more native feel, instead of implementing a rudimentary navbar on the main WebView to go back.
**Attempted Workarounds:** I've attempted to get similar functionality by capturing the onNavigationStateChange event in the WebView, and then within calling goBack + pushing the new view to the navigator stack. From a functionality standpoint, this works. However, from a UI standpoint, the user can clearly see the webview change states to a new page + go back before having the new view pushed on top of their nav stack.

Summary: Fixed broken scaling logic in Webview example for iOS. Pages must be reloaded after toggling `scalesPageToFit`, but that wasn't happening.

Summary:

https://github.com/facebook/react-native/pull/5494 added a new `source` property to WebView on Android that provides a better API, as well as allowing for request headers to be set.
This diff ports that functionality over to iOS, so we can have a consistent API cross-platform.
I've also extended the API to include `method` (GET or POST) and `body` when setting the WebView content with a URI, and `baseUrl` when setting static HTML.

Original github title: Exported a callback for native webview delegate method shouldStartLoadWithRequest
We have a requirement in our app, to open in mobile Safari, any http:// and https:// links displayed in a web view. Our web view is not full screen and is loaded with an HTML string from the backend. Displaying external content in that web view is outside of the scope of our app, so we open them in mobile Safari.
I've forked the WebView component and added a callback property, shouldStartLoadWithRequest, and modified the RCTWebView implementation of `webView:shouldStartLoadWithRequest:navigationType:`
to check if the shouldStartLoadWithRequest property is set.
If the property is set, `webView:shouldStartLoadWithRequest:navigationType:` passes the URL & navigationType to the callback. The callback is then able to ignore the request, redirect it, open a full screen web view to display the URL content, or even deep link to another app with LinkingIOS.openURL().

Summary:
Currently, the system for mapping JS event handlers to blocks is quite clean on the JS side, but is clunky on the native side. The event property is passed as a boolean, which can then be checked by the native side, and if true, the native side is supposed to send an event via the event dispatcher.
This diff adds the facility to declare the property as a block instead. This means that the event side can simply call the block, and it will automatically send the event. Because the blocks for bubbling and direct events are named differently, we can also use this to generate the event registration data and get rid of the arrays of event names.
The name of the event is inferred from the property name, which means that the property for an event called "load" must be called `onLoad` or the mapping won't work. This can be optionally remapped to a different property name on the view itself if necessary, e.g.
RCT_REMAP_VIEW_PROPERTY(onLoad, loadEventBlock, RCTDirectEventBlock)
If you don't want to use this mechanism then for now it is still possible to declare the property as a BOOL instead and use the old mechanism (this approach is now deprecated however, and may eventually be removed altogether).
Summary:
Android WebView now supports the prop "injectedJavaScript", too.
It's time to rename "injectedJavascriptIOS" to "injectedJavaScript" for API
consistency between IOS and Android.
Summary:
@public
The API and implementation of `shouldInjectAJAXHandler` is very opinionated, and it does not solve many of the use cases that we'd like to address.
Since `shouldInjectAJAXHandler` is basically juts injecting JS to the web page, we should let developer inject whatever JS that address different issues that they want to fix.
Test Plan:
Test this snippet at <Playground />
```
<WebView
url="http://www.facebook.com"
injectedJavascriptIOS="document.body.style.border='solid 10px red'"
/>
```
