Idea: Rename feeds

[hyperfekt]

For various reasons feeds could have an uninformative name, for example when subscribed to subfeeds of publications, which cover only part of a topic but their name doesn't show that. There are quite a few scenarios.
I propose being able to change the display name of a feed.
