Add remotenickformat-zerowidth.tengo to contrib

[qaisjp]

Example situation:

• User qaisjp is on both Discord and IRC with the same username
• Whenever @qaisjp (Discord) speaks, a message is sent to IRC like <qaisjp> message.
• Because the IRC username is in that string qaisjp receives a notification on IRC which can be very annoying.

This pull request includes a zero-width space between the first and second character of qaisjp so that IRC clients are not nickalerted by usernames.

This is currently in use and currently works. This is also a common solution for many bridges.

Unless i'm mistaken, that option already exists? https://github.com/42wim/matterbridge/blob/master/matterbridge.toml.sample#L150

But it's a good example of a tengo script!
Thanks!

#The string "{NOPINGNICK}" (case sensitive) will be replaced by the actual nick / username, but with a ZWSP inside the nick, so the irc user with the same nick won't get pinged. See #175 for more information

Whoops, I had no idea that existed! Cheers 🙂

Not sure the script is worth being in contrib now, maybe it would be better to add this as an example in the wiki and say that you can actually use {NOPINGNICK}.

[42wim]

I disagree, it's a good example of the tengo "power" :)
I also recently updated the documentation with all the settings on the wiki:
https://github.com/42wim/matterbridge/wiki/Settings#RemoteNickFormat

Next up is refactoring the matterbridge.toml.sample :-)

Very nice page!
