Notify all frontends of new accounts.

When a new account (wallet) is created with the createencryptedwallet
JSON method, all frontends, including the one requesting the wallet,
must be notified of this new account and its balance (probably zero).

This removes the need for frontends to poll and check for any new
accounts.
