Watch-only addresses in the wallet
==================================
The wallet can now track transactions to addresses (or scripts) for which you
do not have the private keys.
This can be used to track payments without needing the private keys online on a
possibly vulnerable system. In addition, it can help for (manual) construction
of multisig transactions where you are only one of the signers.
One new RPC, `importaddress`, is added which functions similarly to
`importprivkey`, but instead takes an address or script (in hexadecimal) as
argument. After using it, outputs credited to this address or script are
considered to be yours.
The following RPCs have optional support for watch-only addresses:
`getbalance`, `listreceivedbyaddress`, `listreceivedbyaccount`,
`listtransactions`, `listaccounts`, `listsinceblock`, `gettransaction`. See the
RPC documentation for those methods for more information.
Compared to using `getrawtransaction`, this mechanism does not require
`-txindex`, scales better, integrates better with the wallet, and is compatible
with future block chain pruning functionality. It does mean the address needs
to added to the wallet before the payment, though.
