[TIMOB-25703] Android: Add VideoPlayer "showsControls" property

*Summary:* As of Titanium 7.0.0, we've added VideoPlayer.showsControls property for iOS to show/hide the overlaid video controls. We should do the same on Android for parity. http://docs.appcelerator.com/platform/latest/#!/api/Titanium.Media.VideoPlayer-property-showsControls *Test:* Once this feature is implemented, run the below code on Android and verify that the video player does not show any overlaid controls when the video is tapped on.

var window = Ti.UI.createWindow({ fullscreen: true });
var videoView = Ti.Media.createVideoPlayer(
{
	url: "http://download.blender.org/peach/bigbuckbunny_movies/BigBuckBunny_640x360.m4v",
	autoplay: true,
	showsControls: false,
	scalingMode: Ti.Media.VIDEO_SCALING_ASPECT_FIT,
	width: Ti.UI.FILL,
	height: Ti.UI.FILL,
});
window.add(videoView);
window.open();
