- Removed spurious int casts (these are truncated anyway and will break
  doubles)

- Applied the Distance, GetLineLength, EuclideanNorm, DEG2RAD, RAD2DEG
  ArcTangente and NORMALIZE* functions where possible

- ArcTangente now returns double and handles the 0,0 case like atan2, so
  it's no longer necessary to check for it before calling

- Small functions in trigo moved as inline

Charras beat me on fixing the include/sch_item_struct.h include issue from 4069

Fix wxString.Print call to be compatible with wx2.8, thanks to Барановский Константин and Edwin van den Oetelaar for submiting same patch, same hour, are you twins? ;)

Allow plugins to be reloaded without closing/opening pcbnew, next step is plugin editor, just a few lines away...

LOCALE_IO toggle implementation for locale switches on scripting; code cleanups to comply with kicad coding style policy

wxT added to the locales fix, message box on python exceptions inside wizard, added some missing copyright notices

Fix for locales that set , as a decimal point (which is incompatible with python scripting), also fixed the m_Reference encapsulation in module to Reference()

Reverted back the ( i ) parameters for python, applied the PyGILState_Ensure from Dick into his PyLOCK class

improvements to python's GIL acquisition and release, but not done yet, since I think the GIL needs to be acquired even when not involving wxPython.

* Improve the stable and testing build version option logic.
* Use CMake FindPythonInterp to configure the Python interpreter.
* Use Python interpreter to determine the system Python module install
  path if not already defined on the command line.
* Add header symbol checks for asinh(), acosh(), and atanh().
* Add test source to check for isinf() which can be defined as a C++template.
* Replace conditional compile on windows systems for aXXXh() with CMake
  configuration tests.
* A few minor MSVC compile fixes.
* Fix incorrect python environment string in fixswigimports.py
* Create a separate document for KiCad CMake build options.
* Create a separate how to compile KiCad on Windows document.

 Make scripting version compilable on platforms where the python executable is not python2 (define it by -DPYTHON_EXECUTABLE=<python executable filename>)

switch to new s-expression format for footprint exports, use english layernames for naked footprints, dodge conflict with pythons HAVE_GETC_UNLOCKED

Pcbnew: fix  compil warning and a minor bug in plot negative (frame fer plotted in white therefore not visible).
minor code cleaning

pcbnew scripting: cleanup, renamed KICAD_SCRIPTING_EXPERIMENT to KICAD_SCRIPTING_WXPYTHON, now every flavour compiles

Footprint wizard converts from user units to internal units back and forth, so user can type in mm or mils now

* Footprint wizard C++ generic classes
* Footprint wizard C++ to python wrappers 
* Automatic plugin loader from ~/.kicad/plugins
* Python plugin architecture: Footprint wizards

detect building status of the swig .py file (on parallel make builds). Fix unit conversion returns (From_xxx) to integer, what's all the wxPoint/wxRect/wx.. expect. Extended createPcb.py example
