Basic chat addon - Whispers users facts about wombats when they use the word "Wombat".
-Code is triggered when:
-Anyone says "Wombat" in any audible channel.
-If multiple people have addon installed in a guild, only one of them will send the message.
-Facts must be added manually for now.
-No interface what-so-ever
-Still many bugs.
TODO:
-Add interface, and options to turn features on/off.
-Fix bugs, where internally used tables get confused.
