RCON upgrade with additional logging system improvements:
* Netconsole's can now log received messages in color, even when the RCON server has ANSI colors disabled; logs are fully composed locally.
* RCON server now also sends the log type over the wire, along with the (already existing) context.
* SDK logging code is now shared with the standalone netconsole application.
* Improved logging readability for the standalone netconsole application.
