New model sort option

It looks like the new features just keep coming (while image search remains dead). We have a new sort option on the Models tab called "Hot". 🥵 Wait, no, not that kind of hot. It uses an new weighting system based on ratings, downloads generations and publish date.

Here's the formula.

engagement = thumbsUpCount + downloadCount / 6.4 + generationCount / 4.1
hotScore   = round((log10(1 + engagement) + publishedAt_epoch / 2592000) * 10000)

It's live now, and apparently is the default sort now instead of "highest rated" and "month" time period.
