Android InAppBrowser option to not use fullscreen layout

Feature Request

Motivation Behind Feature

Provide an option to conditionally set FLAG_FULLSCREEN for window flags when creating main dialog.

Feature Description

On Android, defaulting to FLAG_FULLSCREEN, hides the Android title bar / status bar. It would be nice to have an InAppBrowserOption to set another flag option to show the status bar.

It is also worth noting that the title/status bar disappears from view in android even if the "hidden" option is set to "yes".

Because of this, briefly opening a hidden browser in the background can create unpleasant resizing/flashing when the android title/status momentarily goes away and then comes back.

Did not have this issue in 3.0.0 and I suspect the above is the reason. In 3.0.0, opening a hidden browser did not make the android title/status disappear.
