Revert screen mode config variables when change not accepted

Browse source 
When changing the screen width, height or refresh rate config variables to 0 or negative values, which are not allowed by the backend, automatically revert the config variables to the actual values again to ensure that the config variables stay in sync with the state of the window. This fixes the client crashing in the graphics settings when setting the screen width and height to 0 via the console, which causes a division by zero when calculating the aspect ratio.
