This updates some of the footprint wizard values to use the default KLC
values for silkscreen, fab, courtyard and text.
Also updates the default QFN settings to create a valid footprint
*) Extend SWIG support deeper into the BOARD class.
*) Move swig *.i files into a directory identified for SWIG, in preparation
for a parallel universe involving Phoenix's SIP.
*) Move swig files which will be common to both eeschema and pcbnew into
common/swig.
*) Sketch out a "common" python module, and plan on dovetailing that into a
libkicad_shared.{dll,so}
*) Add common/swig/ki_exceptions.i and define a macro HANDLE_EXCEPTIONS()
which is to be applied to any function which needs C++ to python
exception translation.
*) Move the test for SWIG tool into top level CMakeLists.txt file for use
in all python modules beyond pcbnew, i.e. eeschema and common.
*) Add SWIG_MODULE_pcbnew_EXTRA_DEPS which generates a better Makefile, one
which rebuilds the swig generated *.cxx file when one of its dependencies
change.
*) Re-architect the board.i file so that it can be split into multiple *.i
files easily.
*) Make some KIWAY from python progress, in preparation for Modular KiCad
phase III.
