PlayerGUI - Captcha with a GUI.

Notes:

• This is not a free version of the already existing Captcha (premium) plugin.
• This is actually different from my previous Captcha plugin, because this will need the player to click on an item in an inventory.
• This is NOT a 2nd version of PlayerUI (my plugin). This is actually a 2nd version of Captcha, but I don't want to name it Captcha 2, because.. Just not ^^

Features:
When a player joins, it will open an inventory (chest) for him, and all he have to do is to click on the green wool.
The chest size is 9*6 (54 block), there is just one green wool and all of the others are red wools, it is hard to detect the good one (the green wool's slot is randomly generated)
Doesn't allow the player to close the inventory , drop item or interact (used for pick up item ). It also doesn't allow to send a message , execute a command or to move , but that's only possible with a modified minecraft client.

Very useful for lobby (BungeeCord) servers. Just install this plugin to the lobby, and it should block all bots. No antibot needed, but you can install one if you don't fully trust this plugin, and then you have 100% security.

There is no configuration to configure the kick-delay for example. I will add it if you want.
