[PATCH] Make 'submodule update' honor the 'update' setting in .gitmodules.

[Mikhail Glushenkov <the.dead.shall.rise@gmail.com>]

Make the 'submodule update' command use the 'submodule.$path.update' setting in
.gitmodules unless this setting is overridden in '.git/config' or with
--rebase/--merge options.
