Kicad: bug fix: in zip project command: filenames are now quoted in command string. Previously if files have space or other exotic character in name, zip fails.

Pcbnew, Module Editor: fix bug 707692 and other potential crashes (when having a block command in progress and try to make an edit command)

This was due to a duplicate constants ( with sligtly different values)  used to select items in some seach functions that broke filtering. Old definitions removed.

* Boost container release method clobbering sheet pointers causing
  seg faults.

* Use Boost pointer container for sheet hierarchy object.
* Add test for modification in sheet hierarchy list object.
* Add method to clear modification flag in sheet hierarchy list object.
* Improve Doxygen comments for sheet hierarchy list object.
* Remove redundant definitions in prototypes header file.

* Move schematic wire and bus break code into schematic screen object.
* Move schematic test for dangling ends into schematic screen object.
* Remove left over debugging output in schematic screen object.
* Remove unused file eeschema/cleanup.cpp.
* Fix bug in schematic line object hit test algorithm.
* Fix a string concatenation compile error added in r2752.
* Rename class WinEDA_BasicFrame to EDA_BASE_FRAME.
* Rename class WinEDA_DrawFrame to EDA_DRAW_FRAME.
* Rename class WinEDA_DrawPanel to EDA_DRAW_PANEL.

Minor others fixes and enhancements

Pcbnew: bug fix: m_ZoneMinThickness parameter not copied in zone copy function. In copy block, copied zones have an erroneous m_ZoneMinThickness parmeter value.

* Encapsulate file name member of base screen object.
* Encapsulate associated screen member of schematic sheet object.
* Create add screen method to schematic sheet object to simplify setting
  the associated screen.
* Move the change file name code in the schematic sheet object to the edit
  sheet method in the schematic editor frame object to eliminate message
  dialogs.
* Improve reference counting in schematic screen object.
* Add helper type definitions for changing schematic object storage to C++
  containers.

Other minor fixes

  * TokenList2DsnLexer.cmake now supports comments, which start with a leading
    # character, and may be either on their own line or on a line after a token.
  * DSNLEXER::PopReader() now pops even the last LINE_READER* and returns it.
++pcbnew:
  * SPECCTRA_DB now inherits from new class SPECCTRA_LEXER, which led to a great
    deal of simplification and code factoring.
  * Moved specctra keywords into specctra.keywords.

Eeschem: fix bug when moving fields in schematic: incorrect field move for rotated+mirrored components
(added InverseTransform( ) in TRANSFORM class)

Modedit: fix issues when printing a footprint. But needs refinement. Work in progress (mainly "Fit in page" is not working).
Minor code cleaning

  * TokenList2DsnLexer.cmake now wraps each token enum in its own namespace. It
    also no longer setup of the "using" directive in the header file, which was
    bad behavior.  C++ enum values will have name collisions unless the enums
    themselves are different namespaces.
++new:
  * Sweet library is now a DSO/DLL.
  * Brought in SWIG to do a wrap of the Sweet DSO/DLL for unit testing
    and scripting.  The SWIG DSO/DLLs are built separate from the Sweet DSO/DLL
    and are also optional.

commit patch from Kenta Yonekura (adding Japanese language) and add  Kenta Yonekura to translator list in about dialog

Very minor enhancement in module edition dialogs.
Fix a minor bug in design rules editor: in Global Rules Edition: drill values > via diameter not checked
and the first item (track or via) in list was not checked (explains Bug 702177, that is not really a bug)

Pcbnew: fix that prevents loading modules from libraries (footprint name not identified in lib)
Module Editor: Try to fix incorrect printing. Fixed now only for scale 1. Nor working for other scales. (Work in progress).
Gerbview: Known bug: printing not working.
VRML export: Fix incorrect export of 3D shapes rotations when the 3D shape was rotated.

* Rename sch_item files to sch_junction.
* Make global variable g_ItemToRepeat a private member of SCH_EDIT_FRAME
  object.
* Encapsulate SCH_SCREEN reference count member.
