@S commands work in survival

using commans that use @s work in survival mode if you skip the space in front of the @.

example (/give @S tnt) does not work but (/give@s tnt) does

note: only works of owners and operators, not members

this bug can be used to near unlimited potential since (/execute@s ~ ~ ~ gamemode c) puts yourself in creative mode and /give@s command_block give you the ability to use all the other commands through itself.
