Summary:
**Motivation**
In iOS you cannot dismiss alerts by clicking outside of their box, while on Android you can. This can create some inconsistency if you want to have identical behavior on both platforms. This change makes it possible for Android apps to have irremovable/required alert boxes just like in iOS.
This adds an additional parameter to the Alert method. The way to use it is by providing an object with the cancelable property. The cancelable property accepts a boolean value.
This utilizes the Android DialogFragment method [setCancelable](https://developer.android.com/reference/android/app/DialogFragment.html#setCancelable(boolean))
**Usage example**
```js
Alert.alert(
'Alert Title',
null,
[
{text: 'OK', onPress: () => console.log('OK Pressed!')},
],
{
cancelable: false
}
);
```
**Test plan (required)**
I added an additional alert to the UIExplorer project where it can be tested. I also added a part in the Dialog Module test to make sure setting canc

Summary: This can happen now, we shouldn't crash. `showAlert` will crash instead if JS tries to call it.

Summary:
Hi,
This changelist is for fixing a crash issue on Android devices. For detail please see, https://github.com/facebook/react-native/issues/7080
In short, the crash occurred when a RN app with a Alert dialog shown at front switches back after it is destroyed at background due to lack of phone memory.
My fix is to let those Alert fragment classes accessible from android.support.v4.app.Fragment instantiate() function, so that it won't crash. And since other UI will be reloaded whatever, mListener is set to null to avoid any callback happen.

Summary:

The `DialogModule` requires `android.support.v4.app.FragmentManager` which means
every app that wants to use Dialogs would need to have its Activity extend the legacy
`android.support.v4.app.FragmentActivity`.
This diff makes the `DialogModule` work with both the Support `FragmentManager`
(for AdsManager & potentially other fb apps) and the `android.app.FragmentManager`
(for new apps with no legacy dependencies).
Also wrap the native module in the same `Alert` API that we have on iOS and provide
a cross-platform example. In my opinion the iOS Alert API is quite nice and easy to use.
We still keep `AlertIOS` around because of its `prompt` function which is iOS-specific
and also for backwards compatibility.
