This system takes over all the different settings that can be set for different modes.
This introduces the new command: "/vs option [set/clear] [option] [value...]"
Available options (not available for all modes): sound, sound_volume, sound_pitch, hybrid, keep_inventory, message, offset, command, inc_death_stat, vertical_offset, keep_velocity.
Different modes support different options. This system is much easier to implement new options, so if there are any new options you would like, please let me know!
With this change, your configuration will automatically be converted and updated. A backup of the config will be made before migration is started.
