`et -t` does not accept IP address about eternalterminal

[MisterTea]

Interesting, thanks for the clear issue description. I don't believe ip addresses are supported at all. I think what's happening is the "10.96.0.1" is being passed to stoi and turned into "10", and "50005:127.1.1.1:8443" is being turned into "50005". Stoi is very tolerant of malformed numbers.

Would you be willing to write this PR? There's a few parts:

1. Change the parsing code here to accept ip addresses: https://github.com/MisterTea/EternalTerminal/blob/master/src/base/TunnelUtils.cpp#L4
2. Remove this check

   EternalTerminal/src/terminal/forwarding/PortForwardHandler.cpp

   Line 66 in 2f8dfdd

   if (sourceName != nullptr) {

3. If the name exists, use it here instead of hardcoding localhost:

   EternalTerminal/src/terminal/forwarding/PortForwardHandler.cpp

   Line 100 in 2f8dfdd

   SocketEndpoint ipv6Localhost;

@MisterTea would love to help with PR, but sadly I don't know C++
Hope somebody can pick this up.

Do you accept bounties, by the way? If yes, I would happily sponsor implementation of this feature.
