Remove resumeepisodes, use existing data for resumevideos

Removes the resumeepisodes (including retrieving the data), and instead
uses the recommended episode data to build the resumevideos list.

Also changed the resumevideos to sort by lastplayed, so that the most
recently stopped video appears first.
