also ignore the 'bundle' directory

If the 'bundle' directory is present, ignore it during setup/scp. Often has self-referential symlinks which do NOT play will with the scp which does a dereference of all symlinks. This results in infinite copy during setup. There's a similar PR which was merged in Sept for the '.bundle' directory but I've never seen bundler create a dir by that name so that ignore may be unnecessary.
