[EGIT PATCH] Resurrect group filtering options in history pane

[Robin Rosenberg <robin.rosenberg@dewire.com>]

This commit restores the ability to filter on not only the selected
resource but instead all changes in the same folder, same project
or same repository. The filtering levels supported are Resource (no button
pessed), Folder, Project and Repository. Only the highest level has any
effect. The flags are persistent between eclipse sessions in the same
workspace.
