Subject: [PATCH] add git hooks for submodules

A much less intrusive version of #3274 that has effect on checkout / pull / merge,
rather than setup.py.  It does require a user install step,
because you cannot add active hooks to a repo.

+git hooks for IPython
+
+add these to your `.git/hooks`
+
+For now, we just have `post-checkout` and `post-merge`,
+both of which just update submodules,
+so make sure that you have a fully synced repo whenever you checkout or pull.
+
+To use these hooks, you can symlink or copy them to your `.git/hooks` directory.
