Added npm and git autoupdates for slick-carousel

Not sure where the npm and git transitions are, or whether git autoupdate is ready, so I've attached two commits below for the slick-carousel library. The first adds npm autoupdate to the package.json, and the second contains git autoupdate details that will need to merge with (overwrite?) the package.json for this library. See `package-gitautoupdate.json`.

Question, since this library ships with various carousel assets, will the autoupdate work if reduced to `slick.*` in the fonts dir? Please quickly scan the filepaths and let me know if I've written anything incorrectly or inefficiently!

Cheers
