Select: Link Block Series skips hidden and locked type in selected groups

Select › Same › Link Block Series no longer counts hidden or locked type
inside a selected group, or type inside a hidden or locked object there,
as selected. A group that holds only such type leaves the command off, and
the command does not select the other frames of that type's thread.
