Pcbnew: fix issue when KICAD_NANOMETER is defined: when zones use htcth to show zones areas, hatch lines were incorrectly calculated (hunded of thousand lines created)
Eeschema: fix issue in search: search not made in reference strings.
Minor fixes, code cleaning and comment enhancements.

* Remove unnecessary copy constructors from schematic and component
  library objects.
* Add comment to class definitions where the default copy constructor
  generated by the compiler was adequate.
* Add assignment operator to EDA_ITEM, SCH_ITEM, and all schematic
  objects where the default assignment operator generated by the
  compiler would not be adequate.

  * Carve out TITLE_BLOCK from BASE_SCREEN
  * Add include/hashtables.h and put class PROPERTIES in there.
    Change PROPERTIES to use "const char*" as the key instead of wxString.
++eeschema
  * Add shim class SCH_BASE_FRAME which introduces the data model SCH_SCREEN
    to the frame EESCHEMA frame class hierarchy and allows sharing of:
    SCH_SCREEN* GetScreen() const;                              // overload EDA_DRAW_FRAME
    void SetPageSettings( const PAGE_INFO& aPageSettings );     // overload EDA_DRAW_FRAME
    const PAGE_INFO& GetPageSettings () const;                  // overload EDA_DRAW_FRAME
    const wxSize GetPageSizeIU() const;                         // overload EDA_DRAW_FRAME
    const wxPoint& GetOriginAxisPosition() const;               // overload EDA_DRAW_FRAME
    void SetOriginAxisPosition( const wxPoint& aPosition );     // overload EDA_DRAW_FRAME
    const TITLE_BLOCK& GetTitleBlock() const;                   // overload EDA_DRAW_FRAME
    void SetTitleBlock( const TITLE_BLOCK& aTitleBlock );       // overload EDA_DRAW_FRAME

    Add shim class SCH_BASE_FRAME which introduces the data model SCH_SCREEN
    to the frame class hierarchy.

rather than being rejected.

This feature is very useful for electronics hobbyists who use DIY PCB technology 
(both toner transfer and photoresist methods).
Also width correction may be useful for PCB designers who take care of track width etching.
This patch also fixes some minor PS plotting issues.

Pcbnew: Now, archive modules function archives footprints with default orientation (0 degrees) and default side (Front layer)

Eeschema: add compil option in sch_field.cpp to go back to old behavior for field texts justifications (this option is not activated)
Note: only vertical texts have a modified behavior.
Minor other changes.

    It describes paper.  The m_Offset field was dropped since it was only used
    in HPGL plotting within EESCHEMA.  PAGE_INFO instance was moved out of
    BASE_SCREEN (which is on its way out) into both SCH_SCREEN and BOARD.

    Dick Hollenbeck 2011-12-22 rename Ki_PageDescr to PAGE_INFO, encapsulate it in accessors, and move it into the BOARD

* Move SCH_ITEM::Place() code into SCH_EDIT_FRAME so schematic item
  objects no longer have any knowledge of the schematic frame window
  or undo/redo containers.

Fix bug 910364: When a footprint saved in a .mod file is not on front layer and/or not with orientation 0 degree, the Module editor load it incorrectly.
note:  the Module editor save it with default orientation and layer, but the archive function does not, so some footprints can be not editable.
TODO: modify the Archive Function to use the default layer / orientation.

Pcbnew: fix a very minor issue.

size while routing (W, Ctrl+W) didn't update the track in the display
