Add disable_settings to game.conf to get rid of "Enable Damage"/"Creative Mode"/"Host Server" checkboxes (#11524)

This adds support for disable_settings to game.conf. In this you can specify a list of settings that should not be visible in the "local game" (or however it is called nowadays) tab. Enable Damage, Creative Mode and Host Server are supported.
