Case details page doesn't show number of confirmations

[axelsimon]

When looking at the details of NN violations, the number of times this case has been confirmed is not seen on the page.

For instance, at the time of writing, this case has been confirmed 14 times:
http://respectmynet.eu/view/191

Yet, this information is not seen on the page itself, though it is relevant.

Ideally, this information would be displayed in a block either above or bellow the “description” block, and use colours to indicate the violation's heat, as done on the map on the /list page.
