In UI and API, sort packages and vulnerabilities from newest to oldest.

[pombredanne]

When I use the UI and search for packages, or when I use the API, I would like to see results of package lists sorted by version from newest to oldest. Same for vulnerabilities, from newest to oldest.

Why? because I am more likely to be interested by recent and current versions than older versions and older vulnerabilities.

Hi @pombredanne , I have made some changes and testing them on my local server I have firstly imported some packages and vulnerability data and then runned python3 manage.py improve compute_version_rank imporover in order to assign the the version ranking to the packages.
After that I have impletelemented some changes in the views.py (https://gist.github.com/Rishi-source/25e42438c87c26c3b7d1324bba60609f) and I have got these results I am sharing a screenshot of the ordering of the results after implementing these changes which I have provided in the gist.
Please correct me If I am wrong at some point. I also want to ask that have I correctly sorted the vulnerability data on the basis of vulnerability_id or I have to use/make some other field in order to sort them.
