Public interface to be viewable if logged in

[TejaGo]

Currently, a dictionary's public inteface is only viewable if the dictionary has been declared "public". The applies to both anonymous web users and logged-in dictionary editors.

The suggestion is to make it possible for logged-in dictionary editors to view the public interface even before the dictionary has been declared "public".

Suggested by Ondřej Matuška.

When a logged-in user is viewing the public interface of a dictionary that hasn't been made public yet, the UI should say this clearly. The user needs to understand that the "public" interface they are looking at isn't really "public" yet.
