        * commiting my changes to allow multiple instances of a given schematic file within 
a hierarchy:
        ** internally, m_currentScreen has been replaced with m_currentSheet,
                which is a list or 'path' of screens.  The path of screens is used to 
generate
                a series of timestamps, which is converted to flat component reference via 
a look-up
                table in the schematic files.
        ** this means that m_currentScreen is no longer used -- use GetScreen().
        ** GetScreen is virtual, as some of the dialogs keep around a WinEDA_BaseScreen 
pointer.
        ** all sub-sheets in a given schematic must have different names to generate a 
meaningful netlist.

void Change_Side_Module( MODULE* Module, wxDC* DC ) is now member of class BOARD (as asked in todo list)

Plot option in GERBER format Plot (Exclude Edge Pcb layer) modification (now, default = off, and saved in config)

* fixed a bug in hierarchal shematics where a loop (e.g. same file included at different points in the 
hierarchy)  would cause infinite memory use.   
* added a edit footprint hotkey to eeschema, since it seems I'm always editing '0603' '0402' etc. on the 
common components, and it was difficult to edit this information before.
