+2007-Oct-30 UPDATE   Dick Hollenbeck <dick@softplc.com>
+================================================================================
++ pcbnew
+    added BOARD_ITEM::Save() and to all derived classes as well.  Made virtual
+    and removed all UI code from these utility functions.
+    removed WriteDesc() functions from all BOARD_ITEM derived classes, although
+    Keeping old ones in commented out form for a while for reference.  
+    @todo: delete these from *.cpp files eventually.
+    zones.cpp, clean up in prep for enhancements.
++ gerbview
+    fixed bug which came about when BOARD::~BOARD() started deleting the objects
+    that a BOARD owns.  export_to_pcbnew.cpp was not consistent with this 
+    design and was crashing.  Also, export_to_pcbnew.cpp now uses the simple
+    BOARD::Save() function.  It was another place to maintain the PCB file format,
+    rather than simply putting that knowledge into one place like BOARD::Save().

 +cvpcb: listboxes.cpp problem solved: exists only under windows
