Growl support

[Leo Franchi]

hey guys,

I have Growl (OS X system-wide notification system) support ready in a  
git branch.

It is a somewhat intrusive change, as I had to namespace the  
Collection classes, so I ended up touching a whole bunch of files. The  
actual amount of new code though is minimal. As we are going to wait a  
few weeks for 2.0.1, I am gonna go ahead and commit it unless people  
strenously object.

Leo
