  Fixed vulnerability issue with file names

There's a bug (feature?) in Sandstorm that prevents spks with an
improper PGP signature from being installed. This change produces an
spk without PGP signatures, and the future `spk repack` command will
allow you to add/change the PGP signatures in addition to changing app id.
