This is a not-that important cleanup: It would be nice if we would tag or fix all methods with "sent but not implemented��� selectors

if you inspect:

�� �� �� �� SystemNavigation new allSentNotImplementedSelectors


you get 160 methods in Pharo12.

- some are dead code
�� �� �� �� -> we should remove those

- some are methods used for tests
- there might be some that are send to objects with a DNU handler
�� �� �� �� -> we should tag them using the < #ignoreNotImplementedSelectors: #()> Pragma

- some are bugs
�� �� �� �� -> we should fix those

Helo is welcome!

If we fix them all we can add a release test and make sure that code like this never is merged.
