* More common header file compiler fixes.
* Translate French code naming and comments.
* Remove global variable ScreenPcb.
* Dead code removal.

* All header files used to create the PCB common library now compile as
  stand alone code.  This prevents the need to define them in a specific
  order to make source code compile properly.  It should also now be
  possible to relocate the source code to build the common PCB library
  to a separate folder.

Fix minor issues.
Fic compil issue in dimension.cpp with wxMSW 2.8.12 (wxMSW 2.8.12 only).

Edit component in schematic: reduce length of some texts (when translated, give a too big dialog)

* Remove sine and cosine look up tables from trigo.cpp and replace them with
  sin() and cos() math functions.
* Large include file clean up to prevent header ordering dependency build
  failures.
* Translate French code names and comments.
* Lots of coding style policy and doxygen comment fixes.

Fix 2 very minor issues.
