generate names for nameless burrows; check for nil

 ## Fixes
 -@ `nestboxes`: fixed bug causing nestboxes themselves to be forbidden, which prevented citizens from using them to lay eggs. Now only eggs are forbidden.
 - `autobutcher`: implemented work-around for Dwarf Fortress not setting nicknames properly, so that nicknames created in the in-game interface are detected & protect animals from being butchered properly. Note that nicknames for unnamed units are not currently saved by dwarf fortress - use ``enable fix/protect-nicks`` to fix any nicknames created/removed within dwarf fortress so they can be saved/reloaded when you reload the game.
-- `seedwatch`: fix saving and loading of seed stock targets
+-@ `seedwatch`: fix saving and loading of seed stock targets
 - `autodump`: changed behaviour to only change ``dump`` and ``forbid`` flags if an item is successfully dumped.
+-@ `autochop`: generate default names for burrows with no assigned names
