This removes the whereami functionality.

I can't find any clear use case for this in order to make the
'Where Am I' text under the search box any more understandable
than the randomness it is currently. It isn't a common feature on other sites, doesn't
help with the editing experience afaik, and it seems to me like
clutter both in code and design.

Discuss as necessary, this is obviously not a straightforward change.
