Thanks for this series.  I have applied it and pushed it out, along
with a small fix on top.

It works nicely, at least the "NG" variant when comparing trees.
;-)

The non-NG variant shows the raw tree diff, which is uh, a little
uninteresting, unless you are a true core Git hacker...

I tested it on a small-ish repository. The history browser works
quite nicely once the cache starts to get filled.  I don't know
how well it works on bigger repositories.  ;-)

Subject: [PATCH] Move GitResourceNode to ui plugin

Because I am trying to keep the core plugin UI free, allowing it
to be used in headless workbenches, such as from an Eclipse based
build system, we don't want to depend on the org.eclipse.swt plugin.
Relocating GitResourceNode to the UI plugin lets us continue to avoid
that dependency.
