This will add back the transaction fees. Prior to this commit the pool
had to cover the transaction fees. Now for each transaction the full
balance is transferred (RPC Daemon will remove the TX Fee) but two
transactions are added. One for the Debig and one TXFee.
Fixes#203.

a worker is active again. Need to think of a system to do that
automatically.
