* Fix 3D frame issue (3D frame not show) when it is iconized and reactivated by Pcbnew or CvPcb menus (Windows only)
* Add in help menu a direct link to the new doc Getting_Started_in_KiCad.pdf, written by contributors (useful for beginners)
* Fix other very minor issues in CvPcb.
* Update howto doc about translation

* Raise 3D frame in PCB editor and module editor instead of displaying a message
  dialog indicating that the 3D viewer is already open.
* Raise 3D viewer and module viewer in CVPCB to mimic the behavior changed in
  PCBNew.
* Set focus to OpenGL canvas when creating 3D viewer so mouse wheel events
  are handled on Windows without having to click on the canvas.
* Rename 3D viewer frame class from WinEDA3D_DrawFrame to EDA_3D_FRAME.
* The usual smattering of coding policy fixes.

* Move clarification menu icon code from base board item object to the appropriate
  object.
* Remove left over French comments.
* Coding policy fixes.

Pcbnew: Fix bug 811437 . This bug (due to duplicate time stamps), cannot happen with usual boards, only when 2 identical board (from the same .brd file) are append.

* Move menu text code from base board item object to the appropriate
  object.
* Add helper to get board layer to base board item object.

eeschema: add SCH_SHEET_PIN_T in ParentItems collector, convert sch_collectors.* to native unix format

Eeschema: fix bug that crashes libedit (after creating a new pin, repeat it (insert key), delete the new repeated pin and try to repeat)

Pcbnew: fix bug in D_PAD ctor: m_LengthDie not initialized. Disable m_LengthDie read from .brd files,
because this bug breaks compatibility with older version of Pcbnew , and the stored value as most of time no sense.
To enable m_LengthDie reading, see class_pad.cpp

All: use double instead of int to store zoom values.

Speed up DIALOG_LOAD_ERROR::ListSet(), used to display lists of errors ( up to 100 x faster) in DRC or loading lib errors

    aModule->m_LibRef = aModule->m_Reference->m_Text;

It was copying placeholder for RefId (say, R*** or so) to pattern id (say it was RESC2012X55N)...

* Change the minimum required CMake version to 2.6.4 for all build platforms
  except Windows and OSX.
* Move all schematic plot code from plot.cpp into the appropriate schematic
  objects.
* Create SCH_SCREEN plot method to plot all objects in the schematic
  screen.
* Delete plot.cpp and remove it from the CMakeList file.

Altough it is a bad practice to have such files :)

* Move code from function ClearProjectDrawList() into SCH_SCREEN object
  Clear() method.
* Delete eeschema/delsheet.cpp as none of the code in it is ever called.
* Move global spice and net list command line variables into SCH_EDIT_FRAME
  object as priviate members and provide access methods.
* Remove unnecessary header includes from eeschema/sheet.cpp.
* Minor coding policy fixes.

- first, matches are now filtered with component filters (as set in eeschema lib editor);
- second, if two or more matches exist, first one will be accepted in accordance to
  alias file order set in project prefs, and then to order of lines in file.

For example you may have such configuration

.equ:
'100' 'CAP100'
'100' 'RES300' 

C component have filter 'CAP*'
R component have filter 'RES*'

So R with value 100 (IEEE/ESKD short for 100 Ohm) will get 'RES300' footprint,
and C with value 100 (IEEE/ESKD short for 100 pF) will get 'CAP100'.

Also equ read routine is rewritten so it is now gracefully accept UTF-8 and spaces.
