Added additional call function for passing an array of arguments (e.g. with user input)

[WebFreak001]

Because for my function luaEmitEvent(A)(string type, A[] args...) I coulnd't pass an array I made this modification

Needs a unit test.

Also, it looks like it would conflict with the existing call function. What should happen with the following code?

function myFunction(a)
    print(type(a))
end

auto myFunction = lua.get!LuaFunction("myFunction");
myFunction.call([1]);

Should it print table or number? The user could mean either.

Maybe it should be a separate function named something like callVariadic.

thats a good idea to rename it but i dont know nothing about unit tests so I cant add it
