- caching of whether an object exists in inventory was somehow removed
since storage refactoring (or it never worked). Now existence checking
is cached in the sqlite storage backend
- recent changes caused the "tag" (and "payload") columns in the
inventory table in messages.dat to be stored as blobs. Searches by tag
(e.g. pubkey lookups) stopped working. This fixes it.
