feat: allow the /dialog command

[mirkokral]

Allows the /dialog command. This is complimentary to kaboomserver/extras#410 which makes the dialog never be unclosable.

This command was blocked because it would allow players to trivially lock clients by simply repeatedly running /dialog commands on them. Has this changed since then?

I do not know of any kicks with dialog, unless you mean blocking the person's game which is already achievable using sudo craft. The best way to combat dialog spamming is to make a dialog timeout and maybe a /showdialogs command, but the same is achievable with sudo craft, which is arguably even worse because it spams cspy and doesn't allow the person to go to the title screen.

Yes, but that is much slower than /dialog (if done through command blocks, it can only happen every two ticks) and easier to escape.
