BadBoy Integration, or Keyword Blacklist

[kennywasafk]

Just thought I'd make a post regarding potential usability improvement. Not sure if this is something you want to add to the scope of the addon but for me personally it would be incredibly helpful.

At the moment Flash Taskbar alerts you even in the case that the phrase in chat is not actually displayed, for example because it is filtered by BadBoy. This is particularly important when you want to get notifications on people looking to buy something but not sell something.

As I see it there are two ways to go about this:

1. This one is more specific and involves integration with BadBoy itself, to make sure Flash Taskbar understands what messages are filtered out and doesn't alert you if they are.
2. A more general approach would be to allow not just whitelisted keywords but also blacklisted ones, or/and maybe regex for word combinations.

Thanks for maintaining the addon otherwise! Appreciate your work.
