Added support for hiding the web view container. This maintains the browser
session without closing it. The browser window can be repeatedly hidden and
shown.
** This has only been tested on android and ios **
amazon/android:
An additional `hide` action was added to `InAppBrowser#execute`. It is
identical to `show`, except that it calls `dialog.hide()` instead.

firefoxos:
Added a `hide` method that is identical to `show`, indicating it is not
supported.
ios:
Added a `hide` method that is identical to `show`, except that it uses
`dismissViewControllerAnimated`. It checks the value of
`_previousStatusBarStyle`. If it is `-1`, the method returns with no
action performed. If it is not, it is set to `-1.`
ubuntu:
Added a `hide` method that sets `CordovaWrapper.global.inappbrowser.visible` to
`false`.

Added a `hide` method that sets `browserWrap.style.display` to `none`.
wp:
Added a `hide` method that is identical to `show`, except that it sets
`browser.Visibility` to `Visibility.Collapsed` and sets `AppBar.IsVisible` to
`false`.
