[PATCH 13/14] cli: sprinter should be able to print an unsigned long

[Daniel Kahn Gillmor]

In some circumstances, we will encounter an unsigned long, and need to
emit it textually.

For example, in GPGME, the gpgme_signature_t object has members
(`created` and `expires`) that are unsigned long integers.  notmuch
doesn't use GPGME directly, but subsequent changes will make it clear
why we need to do have this capability.
