Toggle the header meters with pound key

Show/hide the header meters with the pound ('#') key.  Useful in cases
where the header is too large and occupies essential parts of the
screen, especially in settings (see #1108).

It is only stored as a runtime state, not a persistent setting; to
remove the header permanently one can delete all active meters.
