EMAIL MARKETING - save every old player v4.0

Plugin is now fully updated and adapted for the latest Minecraft versions!

The config.yml file has also been improved — it is now far more editable and flexible for server owners. A new disclaimer has been added inside the config as well.

We introduced a better email-storage system — emails are now saved in two separate files:
One stores emails together with the player’s nickname,
The other stores raw emails only, so you can easily copy them and import them with 1 click into your email software.

New feature! The total number of players who submitted their email will now be printed in the console every time the server starts.

Added README file

A list of valid email endings in config.yml

A new message shown when a player type an invalid email (you can change it in config.yml)

Every email address is stored in a list in "addresses_raw.txt" file

Minor configuration changes
