Added _EMPTY and Storage.exists() to libbe.storage.base.

There seem to be problems distinguishing between "added but unset" IDs
and "added and set to ''" IDs.  Now _EMPTY lets us mark "added but unset",
and Storage.exists() handles "already added?" more clearly than the old
hack "does .get() succeed?".
