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().
edit and preview removed from additional features and turned into core functionality (always enabled).
