[PATCH 3/5] index: tag text parts with inline PGP encryption as "encrypted"

[Daniel Kahn Gillmor <dkg@fifthhorseman.net>]

Assuming we have GMime 3.0 (which has efficient detection of inline
PGP encrypted blobs) we should be able to mark those messages with the
same tag that we mark PGP/MIME and S/MIME encrypted messages.
