Foreground: White
Background: #0078d7 (blue-ish)
Note: Enable non-adorner based rendering of TextSelection in TextBox and PasswordBox in order to be able to change background color.
Remove use of resx file
Resource files are marked as "Resource" instead
Resources are loaded via resource dictionaries (either from code behind or XAML directly through binding)
Reduce amount of required image conversions
Also fix overlay of 50 percent transparency (is now rendered half transparent correct instead of adding "white fog")
Remove obsolete image as rendering is done directly in code
Also fix rendering of link indicator at correct image position
Also remove setting Icons of all Windows (as default is application icon anyway)
Notify icon moved into Menus class (multiple instances would get multiple icons)
Taskbar logo moved into Menus class (multiple instances would get multiple icons)
joystickHelper moved into App class (Only one watcher for gamepad inputs even when multiple Menus exist)
Simplified event calling of these classes
