Merge https://github.com/friendica/red into pending_merge
add Thomas's Diaspora repair script as include/fixd.php - altered so it can be re-run if necessary with a count of remaining hublocs to be fixed. Some sites are down so it probably can't ever get to zero. The check for a null join is quite an expensive query. It could block your DB for a couple minutes while it runs.
Also some preliminary work on a means to take the channel module out of list/forum mode if a specific mid is requested.
