Basic media support

[arraypress]

The majority of site owners using EDD will be selling music, photos, ebooks, themes, software, etc, however from a front-end perspective (on the pages containing the [downloads] shortcodes) there is no easy way of previewing files without clicking thru to the product pages. Even though I plan to cover this with my theme, I have some suggestions for consideration into Vendd core:

• Add the ability via a content filter that extracts the audio player or an admin metabox to place a small audio preview on the frontend download product boxes, allowing customers to preview without going into the product details/download page. The WordPress default audio player is actually suffice for this without requiring 3rd party libraries/bloat.

• Add gallery/slides support with a full screen mode on the download page and potentially on the frontend pages as per the array theme (check this: https://preview.arraythemes.com/checkout-edd/ and https://preview.arraythemes.com/checkout-edd/downloads/startup-icon-font/).

• Add video support on the download page with an admin metabox to allow a link to be added that replaces the featured image with a YouTube/Vimeo video.

Just some suggestions that might be worth considering for the main theme :)
