Share AntennaPod subscribe link instead of RSS url

[ByteHamster]

Apparently users are confused by RSS links. Because of AntennaPod/antennapod.github.io#303, we can now add a title.

This may expose some user information in ways they don't expect. In particular, people with personal Patreon accounts will end up sharing their credentials with both the intended recipient and antennapod.org.

Short of keeping a list of forbidden RSS hosts (e.g., patreon.com), I can't think of an alternative that will work. (And some users may want to share their credentials... although probably not with antennapod.org).

Well I wouldn't consider this an issue, but if you really want to overengineer this you could also make the short URL a key and encrypt the URL and details in the db.
I would prefer to look at this from a user point of view: I just want to share the episode in an easy way (that may also promote AP) and let's someone else listen to it.
Overcast does it beautifully, it's not that difficult technically, let's just do it? :)
