Automatic Ding Congratulator

You have probably seen those addons out there that automatically say 'ding!' into your guild chat when you level up. This addon forms the other half of that concept - if another person in your raid, party or guild levels, and says 'ding!!!' or something similar in either raid, party or guild chat, it with automatically congratulate them.

Additional features: Ego deflation - despite the requests for it, this addon will not congratulate you when you yourself say ding =Þ
If your guild is anything like mine, then they may feel the need to spam the guild channel with 'ding', for the mere pleasure of watching you helplessly reply to every single message. The addon can be turned off at any time by use of the /gratz chat command
