Use CoinControl to pass custom fee setting from QT.

Browse source 
This fixes buggy behavior where we were temporarily setting and unsetting the
global payTxFee when trying to send a transaction with a custom fee from the
GUI. The previous behavior was inconsistent depending on the order of using the
RPC call settxfee and clicking various radio buttons in the sendcoinsdialog.
The new behavior is that transactions sent with the GUI will always use either
the smartfee slider value or the custom fee set on the GUI and they will not
affect the global defaults which are only for RPC and initial GUI values.
