* Wrap Pgm().OnPgmExit() changes in APP_SINGLE_TOP to build conditionally
when KICAD_SCRIPTING_WXPYTHON is enabled.
* Check the result of loading the correct wxPython version during
initialization.
* Add test to CMakeLists.txt to verify wxPython is installed when
KICAD_SCRIPTING_WXPYTHON=ON.
* Add test to make sure wxPython version major and minor numbers match
the version of wxWidgets found.
* Add code to set the correct version of wxPython to the python scripting
initialization code.
* Minor code simplification in Pcbnew KIFACE main window creation.
This required the additional compiler command line option "-std=c++0x".
2) Switch to unique_ptr from auto_ptr which is C++ deprecated.
3) Change to new English layer names per mailing list discussion, see class_board.cpp.
4) When saving to *.kicad_pcb or *.kicad_mod, identify opportunities to use wildcard
layer sets, for pads so far.
5) Switch to two std::string hashtables in pcb_parser.cpp, away from one wxString based one
for layer names and layer sets mapping. One hashtable holds the mask, the other the index.
Layer sets are only in the mask table.
6) Move "LOCALE_IO toggle" into PCB_IO::Format() since it is a public API function and
caller should find it as convenient as possible to use. LOCALE_IO should handle
nesting OK in the case where public Format() is called from one of the Footprint*()
functions.
7) Drop support for "export module to new library". Creating new libraries will have to
be handled in concert with library table entries, and we've talked recently about
creating a better footprint library manager, one that resides in a DLL/DSO. So
this kind of functionality needs to be handled in there in the near future.
8) Change name of exported PCB_IO module/footprint to *.kicad_mod and not *.emp.
