Add submodule support to git module

Browse source 
This does two things:
* add --recursive option to git clone command in clone().  This will
  initialize all submodules when cloning a remote repository.
* Add submodule_update() and call that from fetch().  submodule_update()
  calls two git commands iff the file .gitmodules exists in the
  repository:
  * 'git submodule sync' - synchronizes the submodules' remote URL
    configuration setting to the value in .gitmodules.
  * 'git submodule update --init --recursive' - initialize and update
    registered submodules to the commit specified in the index of the
    containing repository.

If a repository was cloned without --recursive, submodule_update() will
ensure that the submodules are initialized and updated.
