Changes
** The app now informs the web service to terminate the user session upon logout or app closing.
** The app no longer allows self signed server certificates.
* The app's entire login page is now customizable.
** As a result, the old feature which allows customizers to configure the background image of the login page (bg_portrait.png/bg_landscape.png) is removed. Because it only worked for Xamarin.UWP and can now be done with regular XAML customizing.
