The event CHAT_MSG_COMBAT_HONOR_GAIN is a misnomer and processes dishonorable kills as well. This is an annoying error if you have Lua errors turned on and is not noticeable to most users, so it's low impact. Should fix this and start tracking dishonorable kills, or put in a script that checks to see if user is going form version .6 or less to .7 or higher and run the saved variables through a cleanup process.

Completed for English clients. No localization support at the moment, so not considering those as blockers to close this.
