mod_pubsub_feeds: Fix mixup between feed object and parsed feed Did the HMAC thing ever work?

mod_pubsub_feeds: Create pubsub nodes on module load instead of later Should produce faster feedback of things being wrong.

mod_pubsub_feeds: Track latest timestamp seen in feeds instead of last poll This should ensure that an entry that has a publish timestmap after the previously oldest post, but before the time of the last poll check, is published to the node. Previously if an entry would be skipped if it was published at 13:00 with a timestamp of 12:30, where the last poll was at 12:45. For feeds that lack a timestamp, it now looks for the first post that is not published, assuming that the feed is in reverse chronological order, then iterates back up from there.

mod_pubsub_feeds: Add new interval setting in seconds (old still works) To match most other such settings.

mod_pubsub_feeds: Disable WebSub (formerly PubSubHubbub) by default I have seen no recent evidence of this being used or supported by anything anywhere anymore.

mod_http_oauth2: Always show list of requested scopes Upon further reflection, these are probably too important to hide behind a <details> thing.
