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.

Change in CvPcb: CvPcb now does not use .dcm files, only .mod files to read modules keywords and doc

Change in CvPcb: CvPcb does not use now .dcm files, only .mod files  to read modules keywords and doc

* Remove base screen methods from draw frame object and correct current
  screen methods in derived objects.
* Move restore old wires function code into schematic screen object.
* Make add junction method use current screen position instead of store
  position.
* Move poly line ghosting function into the delete current segment method
  as that was the only place is was being used.
* Add method to base schematic object of testing if object has a label
  that can be incremented.
* Simplified the schematic hierarchy traversing code.
* PCBNew Doxygen warning fixes.

early work on DLL exports for sweet lib, stop using <cstdio> which mingw seems not to like cuz snprintf()

* Add option to disable warping mouse to item found.
* Add code to warp mouse when dialog is closed.

* Changed managed cursor callback definition to include the current
  cursor drawing position.
* Modified all managed cursor callbacks to match new definition.
* Added snap to grid option to base drawing frame object.
* Changed add no connect managed cursor callback to use new position
  parameter instead of the stored one.
* Lots of coding policy fixes.

* Remove unused member variable m_SizeVisu from base screen object.
* Move nearest grid position code into base screen object.
* Add get cursor position method to base screen object.
* Add position parameter to OnHotKey method in base draw frame and all
  derived objects.
* Pass logical position on left mouse button click and double click
  events instead of device position.
* Pass logical position to on right mouse button click instead of device
  position.
* Use logical event position parameter for locating items in EESchema
  instead of the stored position.
* Remove unused position parameter when displaying component edit dialog
  in EESchema.
* Comment out debugging macro in eeschema/template_field_names.cpp that was
  preventing debug builds using wxWidgets 2.8.x.

  * macros.h now has TO_UTF8() and FROM_UTF8() which are working converters
    to and from UTF-8 encoding for any wxWidgets build mode.  We can switch to
    them at any time.  I am using them now for specctra conversions and
    elsewhere where I wanted gauranteed UTF8 encoding.
  * added OUTPUTFORMATTER::Quoted( const wxString& ) to simplify converting
    to UTF8 encoded s-expression atoms.  The recommended technique is now simply:
        out->Quoted( wxString ).c_str()
