Add a field for package base popularity
Create a new field Popularity in the PackageBases table. The field is updated by the popupdate script and reflects the popularity of a package. Popularity is the sum of all votes with each vote being weighted with a factor of 0.98 per day since its creation. Signed-off-by: Lukas Fleischer <lfleischer@archlinux.org>
