* Handle default feed setting

* Rm unnecessary type cast

* Remove premature gate check

* Remove nullable check in onPageSelecting, assume the pager checks bounds

* Use null for default selected feed

* Rm unrelated change

* Remove the concept of __key__

I don't think this concept is consistent.

It's introduced on FeedSourceInfo which is used both by pinned feeds and by useFeedSourceInfoQuery. Pinned feeds use the pinning ID there. But there is no pinning ID for useFeedSourceInfoQuery. So this means this field is sometimes one thing and sometimes some other thing. That is a decent sign that it shouldn't be on that type at all.

It's not used anywhere except the desktop feed enumeration. It seems reasonable to assume there that we wouldn't want to show the same feed URL twice. (And if it does occur in the array twice, IMO we should solve that at the API level and dedupe it on read or next write.) So I think we should just use the URL in that place. (I used the descriptor, which is equivalent.)

* Dedupe pinned feeds by URL on read

* Filter timeline out of mergefeed sources

* Put FeedDescriptor into FeedSourceInfo

* Group saved info with feed for pins

This removes a loop within a loop within a loop.

* Fix Feeds link on native
