Implement expandable row on Transactions page

[deanragnarok]

The design had similar UX to Neoscan, where the user could expand a transaction row to see the basic transaction information without having to go to a new page: http://prntscr.com/pn8080

In implementing this, I think we also need to change the clickable areas on all the tables across the site for consistency, so that only the green copy is hyperlinked and not the row itself. On this page, it will allow the user to click the down/up arrow to expand/close the row, and click the transaction ID to go to the full transaction information.
