builtin/reset: add --recurse-submodules switch

git-reset is yet another working tree manipulator, which should
be taught about submodules.

When a user uses git-reset and requests to recurse into submodules,
this will reset the submodules to the object name as recorded in the
superproject, detaching the HEADs.
