[Suggestion] An Event Handler for "PlayerRecieveMessage"

I haven't dug around the available sources for Bukkit if there is any, however, it would be nice to add an event handler for when each player receives a line of text. It's frustrating being unable to change the format of certain messages such as "Your game mode has been changed". Other messages that are exerted from the console also stress my OCD.

Methods I would like to see are:
event.getPlayer()
event.getMessage()
event.setMessage()
event.setCancelled()

This would be great for styling server text from that obnoxious white and urine yellow. It could also be used to highlight syntax such as a player's name. Take into consideration, Bukkit devs! I am counting on you!
