Title: Feature/blank screen

Hello,

I've added the functionality to blank the screen, that is, show an empty screen. The screen can either be black or white. With the shortcut `B` the current slide will be hidden, or shown again. While hidden the navigation through the slides is disabled.

With the shortcut `W` you can switch the background of the content window from black to white and back again.
