Add the --submodule option to the diff option family

When you use the option --submodule=log you can see the submodule
summaries inlined in the diff, instead of not-quite-helpful SHA-1 pairs.

The format imitates what "git submodule summary" shows.

To do that, <path>/.git/objects/ is added to the alternate object
databases (if that directory exists).

This option was requested by Jens Lehmann at the GitTogether in Berlin.
