[Freeciv-Dev] (PR#15576) don't try to edit pollution

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=15576 >

editdlg.c tries to edit the pollution of a city.  This is impossible 
(it's not sent to the server) as pollution is determined in city_refresh 
based on the amount of shields and other effects.

This patch removes it.
