[EGIT PATCH 24/26] Teach GitMoveDeleteHook how to move a folder recursively

["Shawn O. Pearce" <spearce@xxxxxxxxxxx>]

When the user renames or moves a folder Eclipse passes us one event
to move the entire container and its contents.  So we need to move
all of the files contained within that container in our index.
