Improve documentation for configuring settings #82
Description
The current documentation does not cover changing settings of a save. Settings are saved in 3 places (as far as I'm aware) with these being SpaceEngineers-Dedicated.cfg, Sandbox.sbc, and Sandbox_config.sbc (both sandbox files are stored within the save folder). Some settings (e.g. save name and group id) are set in SpaceEngineers-Dedicated.cfg, while other settings (e.g. wolves and number of backups to keep) are set in Sandbox_config.sbc. This is despite all settings being included in SpaceEngineers-Dedicated.cfg (but only some of them will actually change the settings within the game).
The documentation for setting up a server should mention settings are saved in Sandbox.sbc and Sandbox_config.sbc, and they should be updated there if required.
