Don't send separate messages to announce these events, have mw display
them on receipt of onoff events, if scripted handlers allow it to.

If we dont alter the output string until we have a valid escape sequence
then we dont accidentally forget the current acting colour when bad
sequences are found

implements #38

Also fix and simplify the implementation of mw.command

Fixes #34

Fixes #36

Fixes #33

Seems a bit pointless. Also this is a portability improvement since it
doesn't work on *BSD.

Rearrange the order of the questions new users are asked, use more
welcoming words and separate out the data protection statement into a
config file (/etc/mw/data_usage.txt by default).

Should make it simpler to move logging into the server.

Apparently this is required since readline 6.3

    function handler(ev)

        switch (ev.type) {
        case "message_received":
                msg = ev.data;
                ...
                mw.print("msg.channel.id: " + msg.channel.id);
                mw.print("msg.channel.name: " + msg.channel.name);
                mw.print("msg.channel.topic: " + msg.channel.topic);
                mw.print("msg.channel.soundproof: " + msg.channel.soundproof);
                ...
    }
    mw.onevent.push(handler);

Untested.

Configured with

-UDUK_USE_DUKTAPE_BUILTIN \
-DDUK_USE_INTERRUPT_COUNTER \
-DDUK_USE_EXEC_TIMEOUT_CHECK=check_exec_timeout

Turns out msg->bodylen doesn't include the '\0'. Luckily the json parser
doesn't go further than the first character after the outer '}'.

Lots of constification needed to make sure pointers into the allocated
memory aren't freed.

Replaces bind(K_BIND_SHUTDOWN, ...)

    function handler(ev)
    {
            switch (ev.type) {
            ...
            case "exit":
                    mrodder = ev.data;
                    if (mrodder)
                            mw.print("Your mw session was killed by " + mrodder);
                    break;
            ...
            }
    }
    mw.onevent.push(handler);

Replaces bind(K_BIND_INPUT, ...).

    function handler(ev)
    {
            switch (ev.type) {
            ...
            case "input":
                    line = ev.data;
                    mw.print("You inputted: " + line);
                    mw.say("⭐ " + line + " ⭐");
                    return false; // Suppress normal processing
            ...
            }
    }
    mw.onevent.push(handler);

This reverts commit 46e6dbdd.

I guess gitlab is just bad at rst rendering.

Define a new command ,boop handled by boopCmd:

    function boopCmd(arg1, arg2, arg3)
    {
            mw.print("Arg 1: " + arg1);
            mw.print("Arg 2: " + arg2);
            mw.print("Arg 3: " + arg3);
    }
    mw.command.boop = boopCmd;
