Remove Screensavers to work with latest SteamOS

[4ltc0de]

Following on from by #25, I wanted to minimize the changes and just remove the screensaver code to make the shader part of the plugin work after the removal of SteamClient.Input.RegisterForControllerStateChanges

I don't know enough about SteamOS or plugin development to do so, but I think it would make sense to make the screensaver functionality its own separate plugin anyway

Actually this fork seems to not only have the fix, but more functionality and some code cleanup: https://github.com/mspeedo/Reshadeck
So until a fix gets merged, I recommend anyone seeing this to use that instead

На самом деле в этом форке есть не только исправление, но и дополнительная функциональность, а также некоторые улучшения кода: https://github.com/mspeedo/Reshadeck Поэтому, пока исправление не будет внедрено, я рекомендую всем, кто это видит, использовать его вместо

Thanks! Working
