Use 1 locales file instead of individual files for each langauge.
This makes it easier to keep track of what is missing.
The PR will automatically fix missing locales and throw an error if
anything is incorrect, by running the emulator. That way the person
adding a new locale or new language can just run the emulator once to
populate all the fields, so they can easily begin translating.
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.
