Add hits column with sorting on the items page (back-end)

[kulbabskyy]

Here is very useful feature since we have only total download statistic. The PR will add an extra hits/downloads count column on the items page for the back-end users, to monitor download statistic per software item.

Hope you will find it useful.

I have removed the hits counter on purpose: it's not accurate.

If you are using a caching CDN it is very likely that downloads of public items (i.e. whatever is not locked behind a login) will be served without hitting the server, therefore no hit will be recorded.

If you have public items using external URLs, the update server will list those direct, external URLs. Users will download updates for these items without a hit being recorded.

Eventually the hits column will be dropped altogether from ARS. It has very limited utility and this information is also possible to be extracted from the downloads log.
