Can't register command using built-in JS (ScriptingSupport)

[plutonium777]

hello, I think script support is very very useful, but there is one problem: we cannot register in-game commands and this is extremely inconvenient. Now people have to use dot commands, but sometimes it is unsafe, because the players see each other's commands. And we would also like to see the cancellation of events :)

Done in latest builds (creating custom commands).
