Rewrite wx, use wxWidgets 3 as base and use nif interface

Complete overhaul of wx.
Use nif interface instead of erlang driver interface.
Use wxWidgets interface files as base for doxygen and code generation.
This upgrades the base to 3.1.4.

Change the interface files so we can generate code that is backward
as compatible as possible.

Compatibility with the old 2.8 API

Reduce incompatibility with the old API as much as possible.

Changes to the old API include:
 wxNotebookEvent have been replaced by the wxBookctrlEvent  (NOTE)

 wxWindowDC default creators have been removed
 wxClientDC default creators have been removed
 wxPaintDC default creators have been removed
 wxWindow:setVirtualSizeHints(..) have been deprecated
 wxWindow:makeModal(..) have been deprecated
 wxWindow:makeModal(..) have been deprecated
 wxToolBar add/insertTool without label have been deprecated
 wxStyledTextCtrl some functions have changed args from boolean to int
 wxSizerItem:new() Some args have become options
 Removed depr wxSizerItem:setWindow() use assignWindow
 Removed depr wxSizerItem:setSpacer() use assignSpacer
 Removed depr wxSizerItem:setSpacer() use assignSpacer
 Removed depr wxSizerItem:setSizer() use assignSizer
 wxMenu append/insert/prepend have changed return value and lost IsCheckable argument
 wxListCtrl:setItem/4 changed return value
 wxListCtrl:setItem/4 changed return value
 wxImage::convertToGreyscale opts incompatible
 wxGridSizer::wxGridSizer opts incompatible
 wxGrid API have many changes
 wxGraphicsRenderer:create*GradientBrush(..) uses GradientStops now
 wxGraphicsRenderer:createPen(..) have been removed
 wxGraphicsRenderer:create*GradientBrush(..) uses GradientStops now
 wxGLCanvas API is incompatible
 wxFlexGridSizer::wxFlexGridSizer opts incompatible
 wxDisplay::wxDisplay opts incompatible
 wxCalendarDateAttr:new(ColText [,OptList]) have been removed
 wxBitmapButton:[g|s]etBitmapSelected have been removed
