Don't identify episodes by their title
Steps to reproduce
- Subscribe to a feed, where episode titles are updated.
- Subscribe to a feed, where episode titles are used multiple times.
Current behavior
Judging by the behaviour of this app, episodes of a feed are identified by their title. This creates problems already mentioned in other issues:
While having multiple entries after a title change is a somewhat cosmetic problem, missing episodes are IMHO a serious one. And since both of these issues are several years old and seem to be caused by the same underlying problem, I'm now taking the liberty to create a new issue combining the two.
Expected behavior
This shouldn't happen.
Additional information
Therefore I'd suggest to identify episodes by their GUID and create a fallback mechanism in case a feed doesn't include GUIDs. This fallback should be based on one or multiple feed elements that are more likely to be unique and less likely to change. Using the episode URL, possibly in combination with the pubDate or something else, might be safer. Even continuing to use the title would probably be ok if it happens only in case there is no GUID.
