don't remove obsolete hublocs that have no sitekey - it will remove all kinds of other hublocs it isn't supposed to (e.g. diaspora).

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.
Minor doco
build a channel based thread viewing link when in list_mode and when using the channel module, which will disable list_mode (this was checked in yesterday) for the benefit of viewing threads with the correct identities and comment permissions instead of relying on the semi-random uid chosen by mod/display when viewed by an authenticated remote_user().
