Show more information about expanded link

[llucax]

At the moment the expanded link is shown in the same input box where the user enters the original URL. This is just a very ugly hack which is confusing and it can recursively generate expanded links (at least until noclickd rejects expanding links from itself).

A better approach would be to show the link below the form to create new links, presenting a way to easily preview the link (as in getting all the information that will be displayed when visiting the link).

We should fetch metadata from opengraph:
