Remove support for Growl (in favor of OS X Notification Center)

[nschum]

I don't use Growl anymore, so this will be difficult to test. And I suspect most people don't use it anymore, either.

Please help me out by giving feedback. Is removing Growl support fine these days?

One thing I was always worried about is that in Growl you could indicate that a notification should be "sticky" (i.e. not disappear by itself), which makes sense for Gitifier notifications because otherwise they disappear before you finish reading them, and in Notification Center that wasn't possible, at least at the beginning. If I remember correctly, it was possible to configure an app to show "alerts" instead of "banners", but the user had to do this manually and it was per-app, not per-notification. Is that still how it works?

[nschum]

It's possible to change the default from "banner" to "alert", but since sticky notifications aren't the default either, I wouldn't change it.

I'm not too concerned that its per-app, because there now is just one kind of notification as errors are no longer posted this way. #40

Please do not remove Growl, it's still handy utility.
