display directory of package contents on release page

It is very useful to inspect content of a package without downloading it. Both in Debian and in Go. You can also see .dll's and data files that package may install in some doubtful locations. I propose to steal the concept from Go - look for Files and Directories links (although their meaning is a little different).

'Files' has now been renamed to 'Download Files' (to differentiate from 'Download Statistics').

I'd shorten this to just Downloads and Statistics. Although it is not related to this issue.

I don't disagree with you on that. If you want to make a PR with that change, I'd be happy to merge it.

@nlhkabu I extended the idea a little - #974
I don't have local copy, so I don't know how it looks/

Given that we have renamed "Files" to "Download Files", I've renamed the ticket for clarity. (Also, we have removed the statistics pane, and have an open TODO (#787) to implement statistics and integrate stats back into the UI.)

Nicole is running some user tests in the near future and that data will help her see what users look for when they're trying to find more information about a package, so we can decide whether and how to prioritize this feature. Thanks!
