[Addon] Custom signs, signs borders, greenscreen - for Items

This is not a plugin!
This is an addon for ItemsAdder.

⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️
⚠️WARNING: THIS ONLY WORKS ON MINECRAFT 1.16.5+

Please don't install it on a server where 1.16.4 or lower clients can join.
Please don't. (game crashes)
This happens because Minecraft < 1.16.5 has a bug. Client will crash if the font character put in a sign is bigger than X pixels.

How to install?

• UPDATE TO ItemsAdder 2.1.29 or greather.
• USE ONLY ON MINECRAFT 1.16.5 (client must be 1.16.5, server doesn't matter)
  
• extract the data folder from the .zip file inside plugins\ItemsAdder folder
• use the command /iazip
• (upload the pack on Dropbox if you're using Dropbox and update the config.yml url, then use /iareload to reload the config.yml)
• finished
• now place a sign and write one of these texts in the first line

:welcome_holo:
:welcome_sg:
:exit_sg:
:caution_sg:
:high_voltage_sg:
:glass_sg:
:glass_sg2:
:green_screen:
:gold_border:
:quartz_border:
:wood_border:

How to use the welcome holo?

Spoiler

• Place a sign under the ground and write :welcome_holo: on the first line.
• Then cover the sign using GLASS and a CARPET. It won't work with light occluding blocks.
