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()

EAGLE_PLUGIN now establishes (trace_min), (via_min_size), (via_min_drill), and Default Net's (clearance)
by groking the eagle *.brd info.  This makes it more probable that fewer DRC errors come about on first 
DRC attempt.

* Encapsulate most of the MODULE class.
* Start encapsulating the DIMENSION class.
* Lay some groundwork for EDA_TEXT encapsulation.
* Move cleverly hidden MODULE functions into class_module.cpp.
* Use std::swap to exchange TEXTE_PCB values for undo/redo.
* Remove unused members from MODULE class.
* The usual coding policy and documentation fixes.

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.

Pcbnew: fix issues:   Ensure pads type connector  have a drill size= 0, like SMD pads. Ensure keepout zones have no net.

Pcbnew: Partial merge from pcad2kicad (from Alexander Lunev). Fix an old bug related to pads with offset: sometimes the connection to a zone was not detected.

* Fix all Doxygen warnings except polygon files.
* Add footprint library table tasks to TODO.txt.
* Add definition to drag.h to prevent nesting.
* Coding policy fixes.

Pcbnew: fix Bug #1148785 (pcbnew crashes when using only one layer in autorouter ) , and a minor bug in dialog cleanup.

Still fix minor issues in dialog_edit_module_for_BoardEditor.cpp (noticeable only for non English users)

* Fix spacing and consistency issues and debug warning due to improper flex
  grid sizer in module editor module properties dialog.
* Fix spacing and consistency issues in Pcbnew module properties dialog.
* Fix spelling error in DRC dialog message box text.
