Small hole in API to getch dope on an episode

[vandys]

If you find a feed out there in the wild, you can get podcastindex's information on it by looking up via its GUID or URL.

If you have a particular episode of that out-in-the-wild feed, there's no easy way to get podcastindex's information on that episode; you need its (podcastindex-assigned) ID (which you don't have unless you found it through podcastindex) or its Apple ID (which often is not there). to get its podcastindex episode ID, you thus have to pull all the episodes of the feed, looking for the one whose GUID matches.

I suggest at some point supporting a search "episodes/byfeedid?id=X&guid=Y". From the wild, you can get the podcastindex feedid by one lookup, and then do this query to get directly to the episode's information. (Note, both the feed and episodes each have their own "guid", there would be an argument for the argument to be named "epguid"--"episode's GUID").

Please consider this low priority; my current needs only apply to podcasts which have current subscribers through podbrowser, and I can handle this query locally. But I wouldn't mind supporting all episodes of any podcast at all, and this search would help with that quite a bit.
