#25 Send growl subsequent messages while hidden

[Mathieu Masseboeuf]

This makes adium send events to growl when subsequent
messages are received while adium is hidden.
I wanted to have this cuz as my dock is hidden - I have no clue to
see that I received new messages ... (oh, and I don't like bouncing
icons)

Now the only stuff missing is the pref to enable and disable all that
(from growl)
