Title: Using message box for notifications when no GROWL or DBUS is present.

If you do not want or can not use GROWL for notifications on your computer simply don't install the packages for them. Then a simple modal message box is used for notifications.

I needed this change since I can not get the old GROWL to work on my Mac OS 10.8. The new paid version of GROWL might work but I think there should be an option to run slic3r without purchasing additional packages.
