Add Support for "Who anchored" the transaction to the transaction data model

[OR13]

Observer should note "who wrote the transaction to the ledger"...

[OR13]

maybe this is the "writer" property... which is currently set to "writer"...

[OR13]

maybe add timing information to transactions observed as well....

[gjgd]

yup, we need to use the "writer" property and set it to the ethereum address who made the transaction

Looks like this hasn't been addressed yet?

> db.transactions.findOne();
{
	"_id" : ObjectId("61c4bad88070be268cdd0132"),
	"anchorString" : "1.EiBV7a9R8F83nqph9W8lj3sSHojXKSNMUAkR-t7Ua27uNw",
	"transactionNumber" : NumberLong(0),
	"transactionTime" : 8662822,
	"transactionTimeHash" : "0xcc1c8cedd53e2d61faa2811e4819a0db995be01a8db030d8f49794a9335f3498",
	"transactionFeePaid" : 0,
	"normalizedTransactionFee" : 0,
	"writer" : "writer"
}

Running a ropsten node, it looks like the default value of writer is used in the transactions collection.

@BenjaminMoe this is related to the question regarding blocks raised in the DIF slack.
