Network logging improvements

[helmutbuhler]

Some improvements for developers involving network logging:

• Show IP in player tooltip in DEBUG and INTERNAL builds
• Add DEBUG_LOG message when sending packet is incomplete, when an unknown packet is received and when a packet cannot be sent.
• Consistently print an IP, not just the hex value, in logs.

I also simplified some printing of IP addresses with a new macro PRINT_IP_HELPER. I realize we don't want big refactorings yet, but after expansion this macro should result in the exact same code as before, and it simplifies network debugging in the future. And when we clean up the string handling in the future, we can search for this macro and replace it with a functioncall.

Could we split this perhaps in 2 Pull Requests? One for the fix and another for the logging?

[helmutbuhler]

Hm, okay I'll do that. I was hoping this would be okay since the changes are pretty trivial.

[xezon]

Yes size of this change is totally fine, but they do different things. Aka the logging is not needed if someone just wants the text fix.

[helmutbuhler]

Alright, I just removed the tooltip and LAN Serial change out of this PR and updated title and description

Looks good to me. Will this need a yaml documentation? Perhaps not because it is not user facing.

Not hitting the Approve button yet because we still hold off merging code changes.

Nothing user facing here, so I don't think mention of this in the changelog is neccessary

Not hitting the Approve button yet because we still hold off merging code changes.

In addition, it is worth checking before merging whether the feature can also be implemented for Generals, thus maintaining consistency.
