Description

This PR enables logging with plog in shared modules (netcon and netgames). Previously used DLLmprintf() was no-op.
For each module added new function for initialization and accessing to main logger instance.

Nice work! There are a few DLLmprintf calls remaining, mostly in chat_api.cpp and mt_net.cpp, maybe they should be converted to LOG_SOMETHING as well?

I'll also test on Windows when I'll be on my desktop, you never know what it can do with DLLs.
