UI: improve document detail page

[maraoz]

When I'm on the page confirming existence of the document, I see the
  following information:

    Document information d2d59c63a30049c1c75930db61d398959dc5e32ca27772d9b970f261715c7784

    Document proof embedded in the Bitcoin blockchain!

  I think this is really hard to digest for non-technical users who may
  not even know what a blockchain is.  It would be better to first say
  something like this (on a large font).

    This document was registered on 2014-06-26 at 09:42:00.

  Then you could list technical details in a smaller font for those
  users who know how to interpret it.
