class EDA_RECT: is no more derived from EDA_ITEM, just from EDA_RECT (reason: does not use anything in EDA_ITEM)
issue in cast to wxRect fixed (EDA_RECT accepts negative size, but not wxRect, so the wxRectcast  is normalized now).
This fixes some bugs.
A minor other bug fix in Pcbnew.

subclass DIALOG_SHIM support.
Tried dialog_drc but it has nesting problems due to use of DRCLISTBOX, which
needs to be put into its own header file to untangle.

Add include/dialog_shim.h and common/dialog_shim.cpp for use by wxformbuilder's "subclass a wxDialog" support.
This works, but in my version of wxformbuilder there is a bug which does not properly show the 
subclass property, even though it is still in play.  This happens after saving then loading the *.fbp file.
So it is a nuisance bug, but does not affect functionality.

Remove 2 duplicate icons.
Minor cosmetic enhancements and fixes in popup menus.

Eeschema: fix a bug in bool SCH_LINE::MergeOverlap( SCH_LINE* aLine ): ends point of resulting segment incorrects.
remove unused icon files.

* Remove double Clone() function calls from all classes derived from
  EDA_ITEM.
* Lots of Doxygen comment warning fixes.

* All objects derived from EDA_ITEM now have consistent hit test method
  definitions.
* Remove double function calls from all classes derived from SCH_ITEM.
* Lots of Doxygen comment fixes.

* make 2 bitmaps more visible.
* fix incorrect screen redraw when rotating a component.
* netlist : the pcbnew advanced format can be now stored (persistant option) in project config.

  * Save all visibilities, layer and render, in BOARD and restore on load.

Ckecks more pad parameters in pad editor dialog (previously not tested, so a pad could have some very incorrect parameters)

* when a footprint has  many pads having the same pad name, only the first pad was connected to the net

Pcbnew:
 * graphic_item_properties_base.fbp * dialog pad edit: make some strings more easier to translate.
 * global pad edition: fix a bug that change pad position instead of pad size (round pas only).
Eeschema:
 * fix a bug: new created wires were not alwaes shows until the screen was redrawn.

All: added a standard exit dialog called by int DisplayExitDialog( wxWindow* aParent, const wxString& aMessage )
Called when closing pcbnew, cvpcb and eeschema.
Minor code cleaning: remove duplicate or not used strings (mainly file extensions and wildcards)

wxWidgets 2.9 knows wxSVGFILEDC device context.
Unfortunately, arcs are drawn as pies (this is a feature, not a bug).
This is not correct for Kicad.
So Kicad has its own wxSVGFILEDC (named KicadSVGFileDC) that is basically the same as wxSVGFILEDC,
but with arcs drawn as arcs, not pies.
Note also under wxWidgets 2.8 does not know wxSVGFILEDC , so kicad had already its own SVG device context.

other minor fixes.

any configuration overrides.

Call SetDesignSettings() in PCB_BASE_FRAME::ReadSetup().

Pcbnew: Hight contrast mode: commit last patch from Miguel Angel Ajo Pelayo, which also  fixes an old bug.
All: prepare better compatibility with wxWidgets 2.9.4. Works fine with 2.8.x (I hope...)

ModEdit (and ModView): make "invisible" texts visible. They are not visible in  the board editor, but must be visible in the footprint editor.
Minor doc update.

* Convert Eeschema from manually linked list to DLIST for storing
  SCH_ITEM objects.
* Add helper functions to SCH_SCREEN for appending list of SCH_ITEM
  objects.
* Fix bug in wire editing code for accurate undo/redo behavior.
* Add member to DLIST to append another DLIST.
* Other minor code cleaning.
