Subsurface-mobile on Android: change the splash screen methodology
This is based on post by Ben Laud https://medium.com/@benlaud/complete-guide-to-make-a-splash-screen-for-your-qml-android-application-567ca3bc70af It creates a theme that uses a splash drawable that Android will show immediately when the application is launched. And then starts the QML application with visibility set to false adn only makes it visible (and replace the splash screen) once initialization is finished. We still get a little flicker with the switch from splash to start page to dive list, but over all the experience is hugely improved. And the bug that the splash screen stays around when starting Subsurface-mobile in landscape also appears to be fixed. Fixes #994 Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
