BungeeLoginCore - New login system

BungeeLoginCore
Very easy to set up and use, sha256 encryption, only 1 plugin!

Description
Created this plugin for myself, but will contribute to the community.
This plugin works like any other login plugin, with a few differences: you don't need this plugin in all servers, only in bungee plugins folder. Setup your login server correctly (for example make it very light 512MB ram server with a few plugins to deny any break and a small spawn with text to login or register) and this plugin will do the rest. It will check all players in the server, and if any is unlogged, it will teleport them back to login server and they will be forced to login.
It will check names (for example AsVaidas and ASVaidas), IP (for session and max ip register limit), can store data in yml and mysql.

How to use

1. Upload this plugin to /bungee/plugins folder
2. Start your bungee and stop it
3. Configure the config
4. Setup correctly login server
5. Start the bungee

Commands

• /login | /l - login to the server
• /register | /reg - register to the server
• /changepassword | /cp - change your password
• /register {username} {password} (BungeeLoginCore.op) - register a new user
• /changepassword {username} {password} (BungeeLoginCore.op) - change user password
• /unregister (BungeeLoginCore.op) - unregister a player
• /accounts (BungeeLoginCore.op) - check how many accounts an user has

It's a simple plugin and I don't think i'm going to support it a lot. Bug fixes and similar will be done, just updates could be very slow.
