Merge pull request #4045 
a3e192a replaced MINE_ with ISMINE_ (JaSK)
53a2148 fixed bug where validateaddress doesn't display information (JaSK)
f28707a fixed bug in ListReceived() (JaSK)
519dd1c Added MINE_ALL = (spendable|watchonly) (JaSK)
23b0506 Fixed some stuff in TransactionDesc (JaSK)
80dda36 removed default argument values for ismine filter (JaSK)
d5087d1 Use script matching rather than destination matching for watch-only. (Pieter Wuille)
0fa2f88 added includedWatchonly argument to listreceivedbyaddress/...account (JaSK)
f87ba3d added includeWatchonly argument to 'gettransaction' because it affects balance calculation (JaSK)
a5c6c5d fixed tiny glitch and improved readability like laanwj suggested (JaSK)
d7d5d23 Added argument to listtransactions and listsinceblock to include watchonly addresses (JaSK)
952877e Showing 'involvesWatchonly' property for transactions returned by 'listtransactions' and 'listsinceblock'. It is only appended when the transaction involves a watchonly address. (JaSK)
83f3543 Added argument to listaccounts to include watchonly addresses (JaSK)
d4640d7 Added argument to getbalance to include watchonly addresses and fixed errors in balance calculation. (JaSK)
d2692f6 Watchonly transactions are marked in transaction history (JaSK)
ffd40da Watchonly balances are shown separately in gui. (JaSK)
2935b21 qt: Hide unspendable outputs in coin control (Wladimir J. van der Laan)
