Log Message:
Based on feedback from joerg@ and riastradh@, don't save a persistent
seed file on first startup after all. Primary rationale: it is not
desirable that the predictability of the first boot (whatever that
may happen to be) force an upper bound on the unpredictability of
random seeds for all future dnscache instances. Instead, as before,
let dnscache read 128 new bytes on every startup. Just give it
/dev/urandom instead of /dev/random.

While here, abolish references to LOCALBASE. Bump version.
