I realized last night that at some point one *could* delete from that page.  I
can't find any reference to it checked in the history of SVN but I know it
existed.  I'm not at all sure why it was removed.  I do think it is still
valuable to allow the deletion of *other* workspaces while in a current
workspace however, and again the deletion of the current workspace simply brings
one back to the workspaceSelectionForm.
