bug#17581: A couple of suggestions for etc/TODO

[Reuben Thomas]

1. ECB is now part of CEDET, which in turn is installed in Emacs, so it can be removed from the list of packages to install (search for "ECB").

2. The suggestion for "Save undo information" could say to use undo-tree, which already does that. According to undo-tree.el, it's already copyright the FSF, but it also says it's part of Emacs, which is surely false. The author is Toby Cubitt <toby-undo-tree@dr-qubit.org>, and undo-tree's upstream is at http://www.dr-qubit.org/git/undo-tree.git

I can make these changes if they're deemed apt.
