New query system and some fixes.

New Japanese translation (thank you のなめ). I have no idea what does it mean )) But it's the nickname of this guy in Discord.

Delete settings table from you database and launch the installation again.
Drop columns motd and query_port from servers table in your database.

Better to replace the whole pages, core, proccesing folders. And template/includes/head.php; install.php; languages/english.php

The list of changed files (I could forget something)

install.php
pages/server.php
pages/admin_server_edit.php
pages/server_edit.php
pages/server.php
pages/submit.php
pages/admin_servers_management.php
core/functions/general.php
core/functions/PHPMailer_new
core/init.php
core/classes/Servers.php
core/classes/MinecraftPing.php
core/classes/MinecraftPingException.php
template/includes/head.php
