These patches add --progress and --dissociate options to git submodule.

The --progress option existed beforehand, but only for the update command and
it was left undocumented.

Both add and update submodule commands supported --reference, but not its pair
option --dissociate which allows for independent clones rather than depending
on the reference.

This is a resubmission with comments from Stefan Beller and Eric Sunshine
addressed.

  submodule: clean up subsititions in script
  submodule: add --progress option to add command
  submodule: add --dissociate option to add/update commands
