Defines functions drop_media

Documented in drop_media

#'Returns a link directly to a file.
#'
#'Similar to \code{drop_shared}. The difference is that this bypasses the
#'Dropbox webserver, used to provide a preview of the file, so that you can
#'effectively stream the contents of your media. This URL should not be used to
#'display content directly in the browser. IMPORTANT: The media link will expire
#' after 4 hours. So you'll need to cache the content with knitr cache OR re-run
#' the function call after expiry.
