don't build chocolate-setup.6 anymore; more subs

Build chocolate-game-setup.6 directly instead of building
chocolate-setup.6 and copying it to for each game. Apply
substitutions to the template text to replace Chocolate,
chocolate etc., as well as substituting the proper default
cfg equivalent (e.g. heretic.cfg) for each game.
