Database & config cleanup

Removes the old tgstation database, moving all old functions over to the new db. Effectively this merges both databases.

Removes the forum SQL stuff as it was completely unused and non-functional.

Moves many options from config.txt to game_options.txt. No real functional change, but this makes it easier to find and change gameplay related options.

Standardises a few things, but particularly the styling of '/tg/station' and 'BYOND' in dreamdaemon messages on server start.
