Revamped help and settings. Added change for issue #124.

Moved in-game properties back to variables instead of being grouped with INI settings. Help for commands are now grouped into commands, Op-commands, and aliases. "gcommands" command will now only reply with original command names and not aliases. Help for aliases is now mapped to original commands. "gcommands" will only reply with Op commands if the issuer has Op privileges. Updated help files to accommodate new format. Removed message to new users who join game channels.
