Bunch of adjustments
Created by: sonninnos
Restart does reset now.
Who needs a hotkey for sound muting, really? Anyway frontend should handle that, not the core. The button was active even when it was not set in Controls menu.
Keyboard layout was all over the place, but not anymore.
Shift on the keyboard was forced to be held down on a press, but now capslock does that.
