This has a nice synergy in that the hash of the top-level manifest is
all that is required to authenticate the entire directory tree.
(That's a Merkle hash, for those playing along at home.)

Ivan: is the format of the antitheft server's response documented
somewhere?  If so, we should throw in the top-level hash along with
the relative url; this will save an extra authentication step since
the hash can be signed along with the rest of the antitheft response.
