F1.) Allows you to disable a component from the Netlist.  Useful for connectors etc.
To exclude a component from the Spice Netlist add [Spice_Netlist_Enabled] user FIELD set to: N

F2.) Allows you to adapt to simulation libraries that require the netlist node 
sequence to be in a different order. To reorder the component spice node sequence 
add [Spice_Node_Sequence] user FIELD and define sequence: 2,1,0  I am using 
LTSpice, but this holds true for any SPICE subcircuit.

Eeschema: fix a *very serious* bug in netlist generation: sometimes the netlist forgets pins for components having more than one part per package, in hierarchical designs.

Gerbview:   Added: read Excellon files created by Pcbnew. The full Excellon command set is not supported, but drill files created by Pcbnew are supported.

* Fix about dialog escape key termination bug.
* Fix edit hot keys dialog escape key termination bug.
* Set schematic editor component properties dialog default button.
* Fix schematic editor plot DXF dialog escape key termination bug.
* Set PCB editor layers setup dialog default button.
* Set PCB editor swap layers dialog default button.
* Set PCB editor net list dialog default button.
* Add comment to UIPolicy.txt about escape key termination requiring proper
  dialog button IDs.

* Set default button on all dialogs that do not already have a defined
  default button.  The only exception is the EESchema net list dialog
  which needs converted over to wxFormBuilder and due to it's design makes
  setting the default button in any tab other than the default tab
  problematic.
* Fix escape key dialog handling bug in EESchema print post script
  dialog.

gerbview: fix an issue when using layer list in toolbar to select layer (back to old layer under Linux)
Refresh screen when active layer is changed from the layer manager.

Gerbview: tweaking code: Now the active layer is drawn on top of other layers. This is an enhancement in stacked draw modes.

others: fix minor issues.

* Remove clearance and net class name read only text boxes from PCBNew
  auxiliary tool bar.
* Display full net class information in message panel when an object that
  supports net classes is selected.
* Move coordinate string conversion function to EDA_DRAW_FRAME object and
  made it more versatile.
* Refresh message panel text when units change.

Pcbnew: dialog plot: make message window resizable, add tool tip and remove unused sizers.

* Move locate function code into schematic screen object.
* Move test for junction needed into schematic screen object.
* Move test for marking connected items into schematic screen object.
* Move delete item function code into schematic screen object.
* Move delete all markers code into schematic screen object.
* Add method for locating multiple items in schematic screen object.
* Fix minor bug in schematic field object hit test declaration.
* Initial encapsulation work on item picker object.
* Remove duplicate doxygen comments from item picker object source file.

All: fix a minor bur annoying issue: incorrect cursor shape after a block command (mainly when a tool is selected)
