[StGIT PATCH 1/5] Allow stack.patchorder.all to return hidden patches

[Catalin Marinas <catalin.marinas@gmail.com>]

A new property, patchorder.all_visible, was added to return only the
applied + unapplied patches. This is used in the "commit" command to
avoid automatically committing the hidden patches.
