Fix to make notifications not crash in 2.3

This removes the progressbar from the notifications on 2.3, which
is much less than ideal. However after blindly debugging for about
a week, I couldn't really figure out a way to make custom views
in Notifications work across both platforms. So this will have
to do until I figure a proper way out.
Update text for Notification to better fit available width
Update IntelliJ file
Minor spacing fix
