wallet: update passphrase user experience.

Browse source 
For users don't want to set/manage a passphrase a default passphrase
"passphrase" will be used during wallet creation.

At startup, the wallet tries to unlock itself using the default
passphrase, or a user provided one (using -p).

Users that prefer a passphrase can override the default one at wallet
creation time using -p, or use the walletpassphrase rpc when
the wallet is running. This will prevent the wallet from auto-unlock,
and preserve the lock-by-default behavior.
