Better handling of dataset page with many files

[scolapasta]

There are likely several other issues like this or related, but to make sure we track, opening this:

We need to consider cases of loading many files and of sorting / filtering.

@mcrosas comments from #2014:

yes, we need for some datasets as soon as possible a way to sort or filter them by category - we could, for example, display the categories as "tags" at the top of the page (if the dataset has any tags), and when you click in a "tag", it filters the files for that category. This is needed son to bring functionality we had in 3.6 that a few dataverses are heavily relying on.

Suggestions of things needed:

• Count of files in the dataset at the top of the page
• Sort by option
• Listing of tags at top of page for filtering

Users also asked about this in RT:

They are particularly interested in how they can sort/filter with tags.

@eaquigley do you happen to have an idea of when this will be implemented? I have a user asking if it will take more than a few months that they will rename their files for now but if its in a few weeks they will wait till this feature is enabled?

Thanks!

@posixeleni @eaquigley @mheppler are there mockups and/or a Functional Requirements document? This sounds like a non-trivial task.
