[EGIT PATCH 10/11] Don't decorate every single resource on repository change

["Tor Arne Vestbø" <torarnv@gmail.com>]

Not all resources have corresponding labels that are visible,
so by using LabelProviderChangedEvent() we ensure that only
the visible labels are refreshed.

The downside is that we lose project precition, so all
projects are included, but only visible labels in those
projects are re-decorated, so it is OK for now.
