Merges from Scitech Branch (George Davison):

Added wxDisplayChangedEvent and triggering in MSW, when display mode changes
this event gets triggered. I don't know what should happen with other OS's
since I am not familiar with how they handle mode changes.

Watcome Version 11 now compiles with wide character support.

Fixed watcom warnings in
	html/htmlwin.h
	imagbmp.h
	listctrl.h
	imagbmp.cpp
	quantize.cpp
	strconv.cpp
	variant.cpp
	dirctrlg.cpp
	treectlg.cpp
	m_style.cpp
	fontenum.cpp
	listctrl.cpp
	ole\dataobj.cpp
	textctrl.cpp
	window.cpp
	xml.cpp

msw/setup.h
	with watcom version 11 it now compiles with wide character support.

xrc/xml.cpp
	fixed memory leak and compile warnings
