Font Library: Sort Google Fonts Collection by popularity

[creativecoder]

What problem does this address?

Right now the Google Fonts collection json file hosted at s.wp.org uses alphabetical ordering of fonts. This requires me to scroll/page through a lot of fonts if I'm browsing for something useful.

It would be better if we could put the fonts that are more likely to be used at the top.

What is your proposed solution?

Google's webfonts API provides a sort=popularity param to list the fonts by popularity (see https://developers.google.com/fonts/docs/developer_api). We could use this when generating the collection.
