Enhancement Request - Star Ratings

[mattstauffer]

From @vootrunner (tightenco/novapackages-issues#45):

Any chance of indicating the date of the last rating for a package (e.g. last rated 15-June-2001) under the rating count? Or perhaps something like "Last rated ** on 01-July-2016"

Packages still feel too much like a roll of the dice. Just bit by another 5 star rated package that just doesn't work.

Moving this to discussion #135
