Fix many doxygen warnings (due to missing info, old comments, typo ...) when building the doxygen doc.

Fix CMake warning caused by removal of boost dependency when not actually building boost from source.

* Move all Windows install subfolders from ${CMAKE_INSTALL_PREFIX}/share/ to
  ${CMAKE_INSTALL_PREFIX}/share/kicad/.
* Remove unused define DEFAULT_FP_LIB_PATH from build configuration.
* Remove Boost target when skipping internal Boost build.
* Update INSTALL.txt to reflect install tree changes.

Fix minor issues about translated strings and coding style. Add comment relative to file function info  in X1 gerber file format.

Pcbnew: Console python: use a wxMiniFrame to show the console and remove the management by a EDA_PANEINFO, which was not the right way to manage this console.

  inverted due to wxWidgets handling of the axis and wheel rotation of shifted events.

  steps to better support devices with precise scrolling deltas (trackpads).
  Scrolling is done in the handler rather than creating and firing cmd events.
  This is intended to support two-finger scrolling on the Magic Trackpad.
- Added a preference, 'Use mousewheel to pan', to allow panning by default
  on mousewheel events.  This reverses the existing behavior where unmodified 
  mousewheel zooms and Shift/Cmd modified pans.  

  The old behavior was:
  - Unmodified scrollwheel performed zoom in/out
  - Shift modified scrollwheel performed pan up/down
  - Cmd modified scrollwheel performed pan left/right
  - Shift+Cmd modified scrollwheel performed zoom in/out
    with no cursor warp

  With the new preference checked, this changes to:

  - Unmodified scrollwheel performs pan up/down
  - Shift modified scrollwheel performs pan left/right
  - Cmd modified scrollwheel performs zoom in/out
  - Shift+Cmd modified scrollwheel performs zoom in/out
    with no cursor warp

  With the preference unchecked, this is now:
  - Unmodified scrollwheel performed zoom in/out
  - Shift modified scrollwheel performed pan left/right
  - Cmd modified scrollwheel performed pan up/down
  - Shift+Cmd modified scrollwheel performed zoom in/out
    with no cursor warp

  It should be noted that for the last case, the behavior has changed.
  This is not arbitrary.  This now matches expected behavior for an OS X
  application.  This also matches what wxWidgets expects on this platform
  as wxWidgets changes the axis of mousewheel events to horizontal when
  the event is shift-modified.

  The preference is added everwhere that mouse preferences previously
  existed, i.e., eeschema, pcbnew and gerbview.  The 3D Viewer does
  not yet honor this preference, but behaves as if it was checked.
  The pl_editor does not currently have any preferences to honor.

  As with the magnify event support, this covers canvases for all
  current tools, EDA_DRAW_PANEL, EDA_3D_CANVAS and EDA_DRAW_PANEL_GAL.

  This does NOT modify the behavior of mousewheel zooming, though it
  probably should.  This remains unsuitable for use with a trackpad,
  use pinch-to-zoom instead.

  
    This was causing scrollwin events to be handled in the wxScrolled
    default handler even if we'd already handled it, resulting in scrolling
    in both the vertical and horizontal direction for a single event.

  Committing this separately from the rest to ease making a patch for just this
  functionality in case that it might make it into the trunk.
  
  This can function standalone, though it is less useful without the rest.
  It requires that wxwidgets-3.0.0_macosx_magnify_event.patch be applied to wxWidgets
  It is completely optional; everything is guarded by the USE_OSX_MAGNIFY_EVENT macro.
  
  - Added OnMagnify event handler to EDA_DRAW_PANEL, EDA_3D_CANVAS and the helper for
    EDA_DRAW_PANEL_GAL, WX_VIEW_CONTROLS. This should cover canvases all current tools.
  - Guarded all with USE_OSX_MAGNIFY EVENT feature macro and added support in CMakeLists.txt

  
    This was originally submitted by Jared Boone in http://trac.wxwidgets.org/ticket/14322
    and has been updaetd to apply cleanly to wxWidgets-3.0 (and less cleanly to 3.0.1 an 3.0.2).
    The ticket is marked as accepted but not scheduled, so no idea if it will ever make it in.

Pcbnew: fix a serious bug in ZONE_CONTAINER class copy constructor: a pointer was not initialized. Pcbnew crashes when deleting or filling a copied zone.
Eeschema: remove dead code and uncrutify class_netlist_object.h

* Add more missing source code licenses.
* Fix coding policy violations (tabs and trailing white space) in Python
  scripting code.
* Add stable release policy to full documentation build.

Kicad manager, Gerbview: When running Gerbview from Kicad manger, set the Gerbview  CWD to the current project directory.
Therefore, when trying to open Gerber files, the default directory is now thecurrent project directory.
(fix Bug #1380088 )

Cvpcb: Add a tool to solve conflict assignments when the schematic netlist and the .cmp file do not contain the same assignment and both are valid fpid.
It happens when footprint assignments are modified outside Cvpcb (when editing the footprint assignment field in schematic)

Kicad manager: fix Bug #1385953 (unable to open .PDF files with spaces in name/path when using default PDF browser).
Fix also an issue when selecting preferred browser.

Eeschema, Plot dialog: add Plot directory selection. The patch from 1383026@bugs.launchpad.net was widely used.

eeschema: fix Bug #1385789 (eeschema segfaults, when editing a new field). Fix an other minor bug in Footprint editor.
