[PATCH v2 1/5] gpg-interface, tag: add GPG_VERIFY_QUIET flag

[santiago@nyu.edu]

From: Lukas P <luk.puehringer@gmail.com>

Functions that print git object information may require that the
gpg-interface functions be silent. Add GPG_VERIFY_QUIET flag and prevent
print_signature_buffer from being called if flag is set.
