Correct transactions parsing and add exchange price.

[username1565]

I think, transactions must be parsed correctly, like here, not in JSON, because some values ​​are unreadable.
List the blocks by this links, and click by each transaction inside.

Also, for each transactions with type "exchange", will be better to show the price of exchange.

But this is not so important, and you can do this just for fun when you'll have free time to do this.

So, I just leave this as separate opened issue.

Also, will be better to add there, where you put the link for transaction page (date and time of each transaction), add the property: target="_blank" for <a href="txid_ling">-element,
to open the page with transaction info in separate tab:

<a href="txid_ling" target="_blank">

And also, will be better to decode base58-encoded value of attachment - to readable text.

You can add, after JSON, and <hr>
the parsed transaction-data
