Import carousels and their content
Browse files Browse the repository at this point in the history 
* Adds support for importing carousel-type posts
* downloads all images and video
* adds them to the post metadata (call get_post_meta() with  $single = false to get an array of all)
* sets the featured image to match the what instagram shows (either the first picture, or the first frame if it's a movie)

This doesn't automatically insert the extra content into the post (yet). I'm doing it with a hook, but I think we need to figure out a better way to make that a built-in feature.

Partially Fixes jtsternberg#43, and superseds / fixes jtsternberg#42
