  GeneralControl().
* Removed unused old mouse buttons global variable.

* Fixed ambiguous call to sqrt() MSVC compiler error.
* Fixed a bunch of type conversion warnings in GCC 3 (MinGW).

* CVPcb now uses wxUpdateUIEvent instead of set toolbars.
* Removed duplicate event handlers in CVPcb that were factored into
  EDA_DRAW_FRAME.
* Fix definition of GeneralControle() in CVPcb that prevented it from being
  called.
* Remove rarely used and scary refresh code GeneralControle() method in all
  main frame windows.
* Factor zoom menu and tool bar command IDs down to EDA_DRAW_FRAME.

* Old control state handling code completely removed in all applications.
* Factor common control state handlers into EDA_DRAW_FRAME.
* Replaced EDA_ITEM test for newness with IsNew() method.
* Factor vertical right toolbar command handlers out of giant edit command
  switch statement in EESchema and PCBNew.

1- incorrect mouse cursor position when clicking on an ERC error message from dialog ERC window to go to the corresponding marker.
2- broken behavior of hierarchy navigator (horizontal toolbar, hierarchy tool)

Tune pcbnew plot dialog. Make actual plotting code independent of dialog widgets and get settings from PCB_PLOT_PARAMS instead.

Pcbnew: dialog plot: use full available height to display layers list.

Pcbnew: remove duplicate definitions of some flags (like EDIT and IN_EDIT) that have exactly the same meaning, but different values... (very dangerous)
Remove obsolete code.

* Rename all member variables and methods that reference the cross hair
  code in draw panel object from cursor to cross hair to eliminate confusion
  between the two concepts.
* Rename cursor capture call backs in draw panel object to improve code
  readability.
* Create helper class for turning off the cross hair while drawing.
* Remove redundant block clear code.
* Remove redundant mouse capture call back reset code when end capture
  call back is called.
* Remove unused function definitions in base draw frame object.
* Lots of minor coding policy and doxygen comment fixes.

Eeschema: intermediate netlist : fix duplicate pins in libpart, with components having 2 shapes (DeMorgan conversion) and somethimes with multi parts per package.

Commit installer translation files for Japanese

Eeschema: in intermediate netlist generation: remove redundant pins list by component, and make Dick happy.
Known bug in intermediate netlist generation: multi parts per package have their common pins listed more than once in nets section. Will be fixed.

* Fix optimized bitmap grid drawing method.
* Enable optimized grid drawing method on Windows and Linux.
* Create a helper class for resetting and restoring device context scale
  and origin settings for blitting purposes.
* Use wxLogTrace instead of wxLogDebug for coordinate dumping in
  drawpanel.cpp.  See comments for more information on enabling coordinate
  tracing.
* Add flag to allow hiding the drawing cross hair.  Hide cross hair by
  default on OSX.
* Move get cross hair device position code from draw panel object to base
  screen object.
* Remove redundant parent member variable from draw panel object by
  overriding wxWindow::GetParent() method.

very minor enhancement in netlist dialog.
Gerbview: remove useless  code I wrote specific to Windows in BOARD::Draw()  function, because Wayne has fixed the bug.
common_plotPS_functions.cpp: remove a potential bug.
Rename some classes according to coding style policy.

* Fix rendering bug in GerbView caused by wxDC scaling change caused by
  setting the wxDC clipping region.
* Eliminate the need to have optional background erasing as the change
  above fixed that problem as well.
* Default cursor handling improvements.

Use non translated fields names in intermediate netlist file because they are keyword in this file.
Change intermediate netlist file extension from .tmp to .xml

* Schematic editor cancel current tool command now use a single command
  ID that is used everywhere the event is generated.
* Moved cancel current tool code from Process_Special_Functions to a
  separate event handler.
* Add idle check method to block select object.
* Add block active check to base screen object.
