EXT-5267 EXT-5268: Add Parcel Media and Parcel Audio items to nearby media panel

Review #109

This (fairly major) change adds new "items" to the media list for
Parcel Media and Parcel Audio. Since these items are special (before
the items were always MoaP impls), they had to be treated
special. Moreover, actions on all of "media" had to be centralized so
that they would have similar behavior.
