/**
* Grabs all available enclosures (podcasts, etc.)
*
* Supports the <enclosure> RSS tag, as well as Media RSS and iTunes RSS.
*
* At this point, we're pretty much assuming that all enclosures for an item are the same content. Anything else is too complicated to properly support.
*
* @todo Add support for end-user defined sorting of enclosures by type/handler (so we can prefer the faster-loading FLV over MP4).
* @todo If an element exists at a level, but it's value is empty, we should fall back to the value from the parent (if it exists).
