Format: Merge all non-Wireguard configurations to [Wireproxy] section

Currently you have TCPClientTunnel [Socks] and [SNI] custom sections. Those are not Wireguard standards and might overlap in the future.

Why not make a [Wireproxy] section and merge those custom options there?
Also make those tunnels more useful.

Example:

[Wireproxy]

# Set up more tunnels by declaring tunnel lines
# Bindaddr , DestTarget

TCPClientTunnel = 127.0.0.1:25565,play.cubecraft.net:25565
TCPClientTunnel = 127.0.0.1:25569,play.cubecraft.net:25569

# TCPServerTunnel
# "VPN":ListenPort , Targer

TCPServerTunnel = VPN:3422,127.0.0.1:25545
TCPServerTunnel = VPN:1234,192.168.23.45:5678

STDIOTunnel = ssh.myserver.net:22
STDIOTunnel = ssh.myserver.net:23

Socks5Proxy = 127.0.0.1:25344
Socks5Proxy = 192.168.23.45:1080
Socks5Username = xyz
Socks5Password = xyz

HTTPProxy = 127.0.0.1:25345

SNIProxy = 127.0.0.1:25345
