Implemented a new debug log type called NetLog and added more verbose logging to the LDN service.
I'd like some feedback on what all should be logged under this category -- I'm likely going to be adding logs for sockets as well, but I want to know specifically if the logging should be more or less verbose and what would be the most helpful things to log.

These changes allow players to matchmake for local wireless using a LDN
server. The network implementation originates from Berry's public TCP
RyuLDN fork. Logo and unrelated changes have been removed.
Additionally displays LDN game status in the game selection window when
RyuLDN is enabled.
Functionality is only enabled while network mode is set to "RyuLDN" in
the settings.
